Quantification of Urine Elimination Behaviors in Cats with a Video Recording System

Abstract

BackgroundUrinary disorders in cats often require subjective caregiver quantification of clinical signs to establish a diagnosis and monitor therapeutic outcomes.ObjectiveTo investigate use of a video recording system (VRS) to better assess and quantify urination behaviors in cats.AnimalsEleven healthy cats and 8 cats with disorders potentially associated with abnormal urination patterns.MethodsProspective study design. Litter box urination behaviors were quantified with a VRS for 14 days and compared to daily caregiver observations. Video recordings were analyzed by a behavior analysis software program.ResultsThe mean number of urinations per day detected by VRS (2.5 ± 0.7) was significantly higher compared with caregiver observations (0.6 ± 0.6; P < .0001). Five cats were never observed in the litter box by their caregivers. The mean number of urinations per day detected by VRS was significantly higher for abnormal cats (2.9 ± 0.7) compared with healthy cats (2.1 ± 0.7; P = .02); there were no apparent differences in frequency between these groups reported by caregivers (0.7 ± 1.0 and 0.5 ± 1.0, respectively). There were no differences in mean urination time between healthy and abnormal cats as determined by VRS or caregivers. Mean cover‐up time determined by VRS was significantly longer in healthy cats (22.7 ± 12.9 seconds/urination) compared with abnormal cats (8.7 ± 12.9 seconds/urination; P = .03); differences in cover‐up time were not detected by caregivers.Conclusions and Clinical ImportanceCaregivers commonly underestimate urination frequency in cats when compared to video‐based observations. Video recording appears to facilitate objective assessment of urination behaviors and could be of value in future clinical studies of urinary disorders in cats.

The association of bacteriuria with survival and disease progression in cats with azotemic chronic kidney disease

“…6 of true UTI. 7 In our study, it was not possible to assess the potential impact of nontreatment of subclinical bacteriuria on either progression of CKD or survival because all cats received antimicrobial treatment, and further work is required to explore this concern. The duration of antimicrobial treatment in our retrospective study also was substantially longer than currently recommended International Society for Companion Animal Infectious Diseases (ISCAID) guidelines.…”

“…6 However, previous research has found that owners underestimate the frequency of urination in their cats, and the prevalence of true UTI therefore could be underestimated. 7 To date, limited information is available regarding the prognosis of patients with CKD and concurrent UTI or subclinical bacteriuria, either in the human or veterinary medical literature. In people with autosomal dominant polycystic kidney disease (ADPKD), UTI is reported as a risk factor for deteriorating renal function.…”

O papel das urolitíases na obstrução uretral em felinos domésticos: Uma revisão de literatura

“…A doença do trato urinário inferior dos felinos (DTUIF) é um dos problemas mais frequentes na rotina clínica, sendo observado alterações no padrão de micção dos gatos acometidos (Dulaney, Hopfensperger, Malinowski, Hauptman, & Kruger, 2017). O perfil dos animais com DTUIF geralmente inclui gatos machos, castrados, sedentários, obesos, entre 1 a 10 anos de idade, domiciliados, que consomem ração seca e bebem pouca água (Martins et al, 2013).…”

Utilização de sonda Foley para desvio temporário do fluxo urinário em felino acometido por ruptura uretral iatrogênica

“…A síndrome denominada Doença do Trato Urinário Inferior do Felino (DTUIF), caracterizada por combinação das enfermidades cistite e uretrite, frequentemente culmina na ocorrência de obstrução uretral. A anatomia peculiar da porção peniana da uretra de felinos machos, com uma leve curvatura, favorece a ocorrência de obstruções, seja por urólitos ou por tampões mucosos oriundos de processos inflamatórios (1)(2)(3)(4).…”
