Domestic cats (Felis catus) are widely believed to be highly sensitive to the effects of social stress, especially when living in high density populations. Cats are capable of adapting to living in a group, but this will often require opportunities for escaping and hiding. In this pilot study, adrenocortical activity, as a valuable physiological indicator of arousal underpinning potential emotional stress, was evaluated through the measurement of mean faecal glucocorticoid metabolites (mGCM) in fourteen singly and sixteen group-housed cats. Living conditions and ratings of the owners' quality of life (evaluated from self-reported questionnaires) were used as factors associated with faecal glucocorticoid levels of the cats. A direct association between the scores of owners' social dimension of quality of life and the cats' mGCM was found for single cats only, with higher owner social scores associated with higher cat mGCM. No significant differences in mGCM were found between singly versus group-living cats. This suggests that the under-explored factor of owner lifestyle could play an important role in domestic cats' day-today levels of arousal, especially when kept as single pets.
A case of acquired skin fragility syndrome associated with hepatic disease in a 9-year-old, spayed female, domestic shorthair cat is described. The cat was admitted to the veterinary hospital of the University of São Paulo (Brazil) with a 6-week history of vomiting, inappetence and weight loss. Remarkable signs were weakness, lethargy and profound jaundice that had been present for 10 days according to the owner. On completion of the physical examination, when the cat was gently manipulated for blood collection the thoracic limb and interscapular skin tore. Liver enzymes and bilirubin levels were all above the normal range. On histological examination of skin and liver, Masson's trichrome stain showed collagen fibre alteration and major hepatocyte abnormalities. Findings were consistent with feline skin fragility syndrome associated with cholangiohepatitis and hepatic lipidosis.
Pesq. Vet. Bras. 34(6):555-561, junho 2014 555 RESUMO.-Investigou-se a ocorrência de nefrolitíase e/ou ureterolitíase em 72 gatos portadores de doença renal crô-nica (DRC), classificados predominantemente no estágio II, segundo os critérios designados pela IRIS -International Renal Interest Society. Destes pacientes, 47 (65,27%) apresentaram litíase renal e ou ureteral. Não houve diferença estatística entre o grupo de estudo (DRC com cálculo) e o grupo controle (DRC sem cálculo) em relação à idade (p=0,274). Apesar disso, os pacientes portadores de nefrolitíase e/ou ureterolitíase apresentaram maiores indícios de lesão renal, caracterizados por diferenças estatisticamente relevantes da densidade urinária (p=0,013) e pelo menor tamanho dos rins direito (p=0,009) e esquerdo (p=0,048). Encontrou-se similaridade entre os grupos em relação a outros parâmetros, tais como as concentrações plasmáticas de cálcio total, cál-cio ionizado, fósforo, sódio, potássio e paratormônio intacto (PTHi). Os valores das concentrações séricas de ureia e bicarbonato diferiram entre os grupos, com valores de p=0,039 e p=0,037, respectivamente. Além disso, foi mensurada a pressão arterial, que se manteve inalterada na comparação entre o grupo de estudo e o grupo controle. Os resultados obtidos reforçam a necessidade de acompanhamento ultrassonográ-fico de todos os pacientes portadores de DRC, mesmo daqueles assintomáticos ou em estágios iniciais da doença. Nephrolithiasis and/or ureterolithiasis were investigated by means of ultrasonography in 72 cats with chronic kidney disease (CKD), predominantly classified in stage II, according to IRIS -International Renal Interest Society criteria. Of these patients, 47 (65.27%) had nephrolithiasis and/or ureterolithiasis. There was no statistical difference between the study group (CKD with calculi) and control group (CKD without calculi) regarding age (p=0.274). Nevertheless, patients with nephrolithiasis and/or ureterolithiasis had greater evidence of renal injury, characterized by statistically significant differences in the urinary density (p=0.013) and the smaller size of the right kidney (p=0.009) and left kidney (p=0.048), measured in the longitudinal plane. There were no difference between groups in the other parameters investigated such as plasmatic total calcium, ionized calcium, phosphorus, sodium, potassium and intact parathyroid hormone concentrations. The values of serum urea and bicarbonate differ between groups with p=0.039 and p=0.037, respectively. Furthermore, arterial blood pressure was measured, remaining unchanged between the groups. One can conclude that nephrolithiasis and/or ureterolithiasis are common findings in cats with CKD and these results reinforce the need to perform image investigation in cats with CKD even in the asymptomatic ones, or those in the early stages of the disease.
A doença idiopática do trato urinário inferior dos felinos (DITUIF) continua sendo um grande desafio para o clínico veterinário uma vez que, apesar dos avanços nas técnicas diagnósticas, sua etiologia continua por ser determinada. O objetivo do presente trabalho é demonstrar as principais semelhanças entre a doença urinária felina e a cistite intersticial humana (CI), principalmente no que se refere à comprovação do caráter neurogênico da inflamação vesical, o papel do estresse na gênese e/ou exacerbação dos sinais clínicos da doença, e os principais achados cistoscópicos e histopatológicos em ambas as síndromes urinárias. Conclui-se, portanto, que além da dieta comercial, podem existir outros fatores com participação na inflamação vesical de felinos com DITUI.
Objectives The aim of this study was to perform a case-control medical evaluation of cats from multi-cat households presenting with inappropriate latrining and spraying behavior. Methods Owners of 18 ‘spraying’ and 23 ‘latrining’ cats with normal control subjects available from the same households were recruited for a case-control study. Otherwise overtly healthy dyads (each dyad consisting of a case cat and a control cat) were brought together to the veterinary hospital of the University of São Paulo for a medical work-up (ie, physical examination, complete blood count, biochemical profile, urinalysis and urine culture, abdominal ultrasound of the urinary system and in females, where possible, cystoscopy). Results Medical problems were identified with similar frequency in the ‘sprayers’ (38.9%), ‘latriners’ (39.1%) and controls of the latrining group (26.1%), but not the controls of the spraying group (5.5%). The difference between ‘cases’ and ‘controls’ from spraying households was significant. Common potential health-related changes include renal insufficiency, cystitis and bladder lithiasis. Renal calculi, higher creatinine levels (within normal reference interval) and ‘glomerulations’ (detected during cystoscopy) were also found in the remaining sprayers and latriners that were considered clinically healthy. Post-cystoscopy, a new form of periuria occurred in two cats (one sprayer and one latriner). Conclusions and relevance These results indicate that spraying or latrining behavior in the home, as well as living with a cat that is not using the litter box as a latrine, are all associated with a higher level of urinary tract abnormalities; living with a cat that is spraying, however, does not have this association. The findings also suggest that both forms of periuria might be associated with interstitial cystitis. We therefore conclude that all cats with periuria need to be carefully evaluated medically and that treatment of latrine-related problems should consider all cats in the house, whereas spraying may be more focused on the individual displaying the problem.
Background Tritrichomonas foetus is an emergent and important enteric pathogen of cats, which causes prolonged diarrhoea in cats.Case presentationThis study describes a T. foetus infection in a seven-month-old, entire male domestic shorthair kitten with a six-month history of persistent large intestinal diarrhoea, faecal incontinence, prostration, apathy and weight loss. Parasites were microscopically observed and confirmed by PCR and DNA sequencing. Molecular analyses were carried out comparing the sequence obtained in this study with T. foetus and T. suis. Retrieved from GenBank. After treatment with ronidazole, the cat showed resolution of clinical signs.ConclusionsThis is the first clinical case of T. foetus infection in a chronic diarrheic cat in Brazil and South America, confirming the presence of this pathogen in this part of the world and highlighting the importance of this protozoa being considered in the differential diagnosis of cats presenting diarrhoea of the large intestine. Our case report enriches our knowledge on the geographical distribution of T. foetus in cats in Brazil and provides further understanding of the clinical significance of feline intestinal trichomoniasis in this country.Electronic supplementary materialThe online version of this article (doi:10.1186/s12917-017-1026-3) contains supplementary material, which is available to authorized users.
