The influence of feeding regimen on body condition in the cat was studied in a sample of the UK domestic cat population (n = 136). Data were collected by interviewing cat owners and assessing body condition of cats in the owners' homes. Four main factors were identified which were related to body condition. These were, in descending order of significance: neuter status, age, frequency of treat feeding, and ad libitum feeding. Feeding regimen as a risk factor in feline obesity is discussed.  相似文献

Successful weight loss in obese dogs and cats is difficult, and even more so in pets who don't exercise regularly or are inactive. Over the past 10 years, physical rehabilitation (or physio‐therapy) as a treatment or wellness modality has been gaining popularity in small animal veterinary practice. This case report describes the use of physical rehabilitation to achieve weight loss and a decreased body condition score in a chronically obese cat. A 7‐year old, female‐spayed domestic, short‐haired cat, weighing 15 lbs, was evaluated by the Nutrition Support Service at Michigan State University's Veterinary Teaching Hospital for a weight management consultation. The cat had a history of chronic obesity and the owner reported feeding a variety of reduced or restricted‐calorie foods, both canned and dry versions, over the previous 5 years. The home environment included three other cats, none of which were overweight. All cats were fed once daily in the evening; separate food bowls were provided for each cat, but multiple water bowls and litter boxes were shared. A course of 8 weeks of physio‐therapy was recommended, with a target weight of 12 lbs identified, to which the owner agreed. Body weight, body condition score and circumference measures of axillary, rib and flank areas were taken at the initial visit, and at 3 weeks and 8 weeks. At the beginning of the 8th week, the cat's body weight had dropped from 15 lbs to 14.2 lbs, and the body condition score shifted down from 9 to 8 out of 9. More dramatically, however, were changes measured in body circumference: from 43 cm to 38.6 cm in the axilla (11% decrease); 50.3 cm to 42.5 cm in the ribs (15.5% decrease); 46 cm to 41 cm in the flank (11% decrease). To the author's knowledge, this is the first report confirming weight loss, reduced body condition score, and altered body composition in a cat as a direct result of physical rehabilitation.  相似文献

Obesity is an important disease with a high prevalence in cats. Because obesity is related to several other diseases, it is important to identify the population at risk. Several risk factors for obesity have been described in the literature. A higher incidence of obesity in certain cat breeds has been suggested. The aim of this study was to determine whether obesity occurs more often in certain breeds. The second aim was to relate the increased prevalence of obesity in certain breeds to the official standards of that breed. To this end, 268 cats of 22 different breeds investigated by determining their body condition score (BCS) on a nine‐point scale by inspection and palpation, at two different cat shows. Overall, 45.5% of the show cats had a BCS > 5, and 4.5% of the show cats had a BCS > 7. There were significant differences between breeds, which could be related to the breed standards. Most overweight and obese cats were in the neutered group. It warrants firm discussions with breeders and cat show judges to come to different interpretations of the standards in order to prevent overweight conditions in certain breeds from being the standard of beauty. Neutering predisposes for obesity and requires early nutritional intervention to prevent obese conditions.  相似文献

Hyperadrenocorticism in six cats   总被引：2，自引：0，他引：2  
The case records of six cats with hyperadrenocorticism presented to the Department of Clinical Veterinary Medicine, University of Cambridge, over an 11-year period were reviewed. Signalment and clinical signs were similar to previous reports but, in contrast to other reports, only three cats had diabetes mellitus on presentation. Abdominal radiographs revealed an adrenal mass in one case, obesity in all cases but no hepatomegaly. The adrenal glands were identified ultrasonographically in three out of six cases. Clinicopathological findings were non-specific. The diabetic cats had a significantly lower serum potassium concentration than the non-diabetic cats (P<0·05). Results of adrenocorticotrophic hormone (ACTH) stimulation tests were supportive of a diagnosis of hyperadrenocorticism in the five cats in which they were performed. Five cats had pituitary-dependent hyperadrenocorticism (PDH) and one had an adrenal tumour. Differentiation between the two forms of hyperadrenocorticism was possible preoperatively in five out of six cats. Adrenal histopathology confirmed hyperplasia in four cats and adenocarcinoma in one cat. Three cats with PDH underwent bilateral adrenalectomy and two of these cats had low, flat ACTH stimulation tests postoperatively and survived for significant periods. The cat with an adrenal tumour underwent partial unilateral adrenalectomy, maintained a positive ACTH stimulation test postoperatively and was euthanased one week after surgery.  相似文献

Three cats with spasticity on one leg or on all four limbs were presented between 1996 and 1998 at the Department of clinical veterinary medicine, Section of neurology, Vetsuisse-Faculty of Bern. The presumptive diagnosis was tetanus. A focal form was present in two cases and generalised tetanus in one cat. All cats had a history of injury at the affected legs respectively at the neck. The first clinical signs were seen between two days and three weeks after injury. The bacteriologic examination of serous fluid from the site of injury revealed an infection with Clostridium. EMG in one cat during anaesthesia showed motor united potentials (MUPs) on the spastic leg. All patients received antibiotics (Penicillin, respectively Amoxicillin/Clavulanic acid and Metronidazol). Supportive aid were initially sedation, wound revision and in one cat nutrition through oesophageal sonde. In a second phase physiotherapy was performed. All three animals were significantly better after a couple of weeks, two cats were without symptoms after eight and five weeks respectively.  相似文献

Type 2 diabetes mellitus (DM) animal models have provided ample opportunity for investigating pathogenesis, as well as to evaluate novel treatment and prevention options for the disease. Because the domestic cat shares a similar environment with humans, it is also confronted with many similar risk factors for diabetes, such as physical inactivity and obesity. Obesity is a significant risk factor for diabetes in cats, and as such, the domestic cat may serve as an ideal model for investigating obesity induced insulin resistance. This study determined changes in insulin signaling genes within insulin sensitive tissues of obese felines. Quantitative RT-PCR was performed to determine mRNA levels of three important insulin signaling genes which have been implicated with insulin resistance: insulin receptor substrate (IRS)-1, IRS-2, and phosphatidylinositol 3’-kinase (PI3-K) p85α. Obese cats had significantly lower IRS-2 and PI3-K p85α mRNA levels in liver and skeletal muscle as compared to control cats. This down regulation of insulin signaling genes in obese cats mirrors that of obese humans and rodents suffering from insulin resistance. Interestingly, preprandial blood tests indicated that our obese cats were no different from control cats with regards to glucose tolerance and insulin resistance, thus indicating that the obese cats used in our study had a moderate level of obesity. Therefore, insulin signaling gene alterations were occurring in insulin sensitive tissues of moderately obese felines before glucose intolerance was clinically evident. As such, the monitoring of key insulin signaling genes may have some important diagnostic value to determine the risk level and degree of obesity induced insulin resistance.  相似文献

OBJECTIVE: To compare morphometric measurements and serum insulin-like growth factor (IGF-1) concentration in cats with and without hypertrophic cardiomyopathy (HCM), and assess the hypothesis that cats with HCM have larger body size and skeletal features and higher serum IGF-1 concentrations than healthy cats. ANIMALS: 25 cats with HCM and 22 healthy control cats. PROCEDURES: Physical examination and echocardiography were performed to classify cats into the HCM and control groups. Data collected from each cat included diet history, body weight, body condition score, lengths of the humerus and 4th and 12th thoracic vertebrae, heart size, head length and width, and abdominal circumferences. Comparisons of these variables were made between groups. RESULTS: Body condition score in HCM-affected and control cats did not differ significantly. However, median head width; lengths of the head, 4th and 12th thoracic vertebrae, and humerus; and body weight in the HCM-affected group were significantly greater than values in the control group. Median serum concentration of IGF-1 was not significantly different between groups. CONCLUSIONS AND CLINICAL RELEVANCE: These data suggested that among the study cats, those with HCM were skeletally larger, but not more obese, than healthy cats. Whether this was attributable to differences in early growth or other causes requires additional investigation.  相似文献

Feline obesity generally results in aberrations to plasma metabolite levels, such as lipid concentrations and lipoprotein composition. This study sought to investigate the resultant effect of obesity on cholesterol lipoprotein composition and circulating adiponectin concentrations in cats. Plasma glucose, lipids (triglyceride, cholesterol and free fatty acid), insulin and adiponectin concentrations, and cholesterol lipoprotein composition were measured and compared between body condition score (BCS) determined normal healthy control and obese cats. Although the obese group demonstrated higher levels of plasma cholesterol, glucose, and triglycerides, as compared to healthy controls, the difference was insignificant thus indicating that the BCS determined obese cats may have been overweight and not morbidly obese. Plasma insulin levels were significantly higher (25–30%) versus healthy control animals thereby possibly hinting at the ensuing emergence of obesity induced insulin resistance. However, the BCS determined obese cat demonstrated a significant reduction (p < 0.05) in plasma adiponectin concentration and a significant increase (p < 0.05) in LDL-cholesterol % as compared to age matched healthy control animals. This would indicate that changes in plasma adiponectin concentration and cholesterol lipoprotein composition may be good early indicators of obesity in cats.  相似文献

Two Scottish Fold mixed cats are described in this report. Case 1 is a mixed Scottish Fold and Munchkin cat. Extremities of this cat resembled the Munchkin cat, while the ear pinna were folded forward like the Scottish Fold cat. Case 2 is a mixed Scottish Fold and American Curl cat. The ear pinna were curled caudally like the American Curl. Severe exostosis in the hind leg was observed in radiographs taken around one year of age in both cats. Both cats were dominant homozygous for c.1024G>T of the transient receptor potential vanilloid 4 gene, responsible for osteochondrodysplasia in the Scottish Fold cat. Cross breeding with Scottish Fold cats could produce unknown phenotypes, and should be avoided.  相似文献

The greater omentum was used to aid in the reconstruction of nonhealing wounds in five cats. In each cat the cause of the nonhealing wound could not be determined. A vascular omental pedicle was created at laparotomy by dividing the dorsal leaf of the omentum at its pancreatic attachments (four cats) or by dividing the ventral leaf at its gastric attachments (one cat). The pedicle was then passed through either the ventral or lateral body wall into the nonhealing wound via a subcutaneous tunnel. The wounds were closed over the omentum after local tissue mobilization. All the wounds healed uneventfully and have remained healed with a mean follow-up period of 2.5 years. Complications included intestinal herniation through a ventral midline exit hole (one cat), presumed abdominal fat herniation through a ventral abdominal exit hole (one cat) and seroma formation (one cat). All of the complications were treated successfully. The omentum should be considered a useful adjunct in the treatment of nonhealing wounds in cats.  相似文献

Total Colectomy with Ileorectal Anastomosis in the Cat   总被引：1，自引：0，他引：1  
Total colectomy with end-to-end ileorectal anastomosis was performed in eight healthy adult cats. Hydration status, body weight, attitude, appetite, and stool consistency were monitored for 24 weeks. Ileal water absorption was determined at weeks 1, 6, 12, 18, and 24 using the double-lumen catheter intestinal perfusion technique with polyethylene glycol as the indicator substance. Bowel adaptation was evaluated by histologic morphometric analysis of full-thickness ileal biopsies taken at the time of total colectomy and at weeks 6, 12, 18, and 24. The anastomoses were examined at necropsy for evidence of leakage and development of strictures. All cats resumed normal activity in 48 hours and maintained or gained weight during the study. Small volumes of watery diarrhea were present immediately after surgery, but by week 1 all cats had a semi-solid nonformed stool. At month 2, three cats developed semi-solid formed stools. One cat had occasional perineal soiling and five cats had at least one episode of hematochezia. There was improvement in ileal water absorption in two cats, and there were significant increases in villus height, enterocyte height, and enterocyte density in all cats. Results of postmortem examination of the anastomosis showed no evidence of stricture in any cat.  相似文献

Traumatic body wall hernias (TBWH) are serious sequelae to traumatic injury in dogs and cats. During the study period, 26 dogs and 10 cats with surgically managed TBWH were identified. Five cases (four dogs, one cat) did not have their hernias identified during the first 24 hours of hospitalization. Bite wounds were the most common cause of TBWH, accounting for 54% of canine and 40% of feline hernias. Twelve cases (nine dogs, three cats) had serious intra-abdominal injuries diagnosed in addition to their TBWH. Seventy-three percent of dogs and 80% of cats survived to hospital discharge. In addition, the authors report the occurrence of a unique cause of herniation, termed an autopenetrating hernia.  相似文献

Affected cats were three Bengals, one male and two females, whose age at onset of lesions ranged from 13- to 20-weeks old. Nasal planum scaling progressed to thick crusting, consequent exfoliation and exposure of underlying erosions. No signs of pruritus or pain were present but mild respiratory signs were noticed. In all cats, haematology and biochemistry were normal, they were FIV and FeLV negative, PCR for herpesvirus, calicivirus and Chlamydia were negative, and viral isolation for calicivirus and herpesvirus was negative. Wood's lamp examination was negative, as were bacterial and fungal cultures. Cytology showed exfoliating keratinocytes. A skin biopsy taken from one case showed no significant changes. Biopsies from the nasal planum of four dead cats with nondermatological conditions (controls) were collected for comparative studies. Morphometry to record the percentage of the granular layer (GL) and stratum corneum (SC) on the total thickness of the epidermis of the nasal planum was performed. The GL and SC accounted for 10.2 and 21.7% of the epidermal thickness in the affected cat, compared to 18.3 and 20.2%, respectively, in the controls. A significant reduction ( P  < 0.02) of the SC thickness was detected in the affected cat compared to controls. No treatment was instituted as all cats underwent complete (two cats) or nearly complete (one cat) resolution. The reported cases share the same breed, age at onset, type of lesions and a similar outcome. A reduction of the SC thickness in one of the affected cats was recorded. Therefore, an underlying congenital condition is suspected that manifests with high epidermal cell turnover and normal keratinization.

A cross-sectional survey of a convenience sample of cats was carried out to determine the prevalence of and risk factors for respiratory tract disease, feline calicivirus (FCV) infection and feline herpesvirus (FHV) infection. Seven hundred and forty cats were studied; samples for isolation of FCV and FHV were obtained from 622 (84%). Data on individual cat and household variables were obtained by questionnaire for each cat and analysed using univariable and logistic regression analysis. Thirty-eight percent (282/740) of cats surveyed had respiratory tract disease. Eighteen of 24 predictor variables were found to be significantly (P<0.05) associated with the presence of respiratory tract disease in a cat on univariable analysis. Following logistic regression, several factors retained significance including isolation of FCV and FHV, younger cats (4-11 months of age) and multiple cat households. A negative association was found with breeding catteries and other types of household in comparison with rescue catteries. Overall, feline calicivirus was isolated from 162/622 (26%) of cats sampled; 33% of the cats with respiratory tract disease were FCV positive compared to 21% of healthy cats. Variables significantly associated with FCV isolation on logistic regression were the presence of respiratory tract disease and contact with dogs with and without respiratory tract disease. Feline herpesvirus was isolated from 30/622 (5%) of all cats sampled; 11% of cats with respiratory tract disease were FHV positive compared to 1% of healthy cats. Variables significantly associated with FHV isolation on univariable analysis included age, gender, and the presence of respiratory tract disease. Vaccination showed a negative association. Logistic regression analysis of the data for FHV was limited by the sample size and the low prevalence of FHV.  相似文献

Two oligodendrogliomas in two domestic cats involved mainly the rostral brain stem, midbrain, fourth ventricle, and cerebellum. Both cats were aged neutered males presenting with clinical neurologic deficits suggestive of a brain stem lesion. Magnetic resonance imaging of both tumors demonstrated lesions with a pattern of heterogeneous contrast enhancement and multifocal lesions in one cat. Routine cerebrospinal fluid analysis was normal in one cat and suggestive of an inflammatory disease in the other. Oligodendroglioma cells were seen in cytospin preparations of cerebrospinal fluid from both cats. In each cat, the tumors occurred intraventricularly in the midbrain and fourth ventricle with aggressive intraparenchymal infiltration. There was extensive growth into the basilar subarachnoid space of the midbrain and brain stem in one cat. One tumor was well differentiated, and the other was an anaplastic subtype. Immunostaining for several myelin- and oligodendroglia-specific antigens was negative with formalin-fixed tumors and with unfixed frozen samples from one cat. In both tumors, component cells of the intratumoral vascular proliferations were positive for human von Willebrand factor VIII antigen or smooth muscle actin. Immunocytochemical reactivity for glial fibrillary acidic protein identified both reactive astrocytes and a subpopulation of minigemistocytes in both tumors. Ultrastructurally, the tumor cells were unremarkable except for their prominent desmosomal junctions and paucity of microtubules.  相似文献

Objective – To establish a reference interval for intra‐abdominal pressure (IAP) measured by urinary bladder catheterization in normal cats and determine if IAP is affected by observer variation, volume of saline instillation before measurement, or subject variables of gender, positioning, body condition score, and sedation. Design – Prospective experimental study. Setting – Private referral center. Animals – Twenty healthy adult cats. Interventions – Sedation with butorphanol, midazolam, and propofol for catheterization of the urinary bladder and measurement of IAP. Measurements and Main Results – A 5‐Fr red rubber urinary catheter was placed under sedation, and IAP was determined using a water manometer with the cats in right lateral and sternal recumbency. Three readings were taken in each position by 2 observers. The cats were allowed to recover with the urinary catheter in place, and IAP was measured in each cat while they were awake in right lateral and sternal recumbency. Conclusions – In this population of clinically healthy cats, median (interquartile range) IAP taken over all measurements was 7.00 cm H2O (5.23–8.83 cm H2O). There was no statistical difference between observers or subject gender. Factors associated with a statistically significant increase in IAP were right lateral compared with sternal recumbency (P=0.002), being awake compared with sedated (P<0.001), having a higher body condition score (P=0.01 and 0.001), instillation of a higher volume of saline into the bladder for measurement (P<0.001), and struggling during awake measurements (P<0.001).  相似文献

OBJECTIVE: To determine peak vertical force (PVF) and vertical impulse (VI) in cats that had or had not undergone bilateral forelimb onychectomy. ANIMALS: 26 healthy adult cats. PROCEDURE: Onychectomized cats (n = 13) had undergone surgery more than 6 months prior to the study. The PVF and VI were collected from all limbs of each cat with a 2-m pressure platform walkway. Cats were allowed to walk at a comfortable velocity, and acceleration was restricted to +/- 0.5 m/s2. Five valid trials were recorded for each cat with all trials collected in a single 1-hour session. All forces were normalized to and expressed as a percentage of the cat's body weight. RESULTS: Gait data were successfully collected in all cats. No significant difference was found for PVF or VI between cats that had or had not had onychectomy. Limb loads were greater in forelimbs than hind limbs for all trials. Mean PVF and VI in the forelimbs of cats in the nononychectomy group were 56.41% and 18.85%, respectively. Mean PVF and VI in the hind limbs of cats in the nononychectomy group were 50.22% and 14.56%, respectively. CONCLUSIONS AND CLINICAL RELEVANCE: Gait analysis was successfully performed in cats with a pressure platform walkway. The absence of differences in PVF and VI between the 2 groups of cats suggests that bilateral forelimb onychectomy did not result in altered vertical forces measured more than 6 months after surgery in cats.  相似文献
