Plain-English summary
A study found that male castrated cats with a higher body condition score (BCS), which measures how overweight they are, are at a greater risk for urethral obstruction, a painful condition that can block their urinary tract. Interestingly, the risk wasn't linked to overall body weight, but rather to how overweight the cat was. Burmese cats were less likely to experience this issue compared to Domestic shorthairs, and non-pedigree cats had a higher risk than pedigree cats. To help prevent this problem, it's important for cat owners to keep their pets at a healthy weight and monitor their body condition.

Abstract
Identifying potential risk factors for urethral obstruction in male cats may help in disease prevention. The aims of this study were to assess whether breed, pedigree status, age, bodyweight and body condition score (BCS) are risk factors for urethral obstruction in castrated male cats using a primary care population. Within this, a specific question was whether any increase in rate of urethral obstruction in male cats due to excess body condition is because of higher bodyweight. A retrospective hospital-based matched case-control study was performed using 195 cases of urethral obstruction in castrated male cats and 195 control consultations for cats presenting to a feline-only first opinion veterinary practice in Brisbane, Australia. The incidence rate of urethral obstruction did not vary significantly with bodyweight but increased with BCS (incidence rate ratio 1.6; 95% CI 1.2-2.1; P<0.001). The effect of BCS was not due to high BCS cats having higher bodyweights. The incidence was lower in Burmese cats compared to Domestic shorthair cats (incidence rate ratio 0.1; 95% CI 0.0-0.4; P=0.001), and higher in non-pedigree cats compared to pedigree cats (incidence rate ratio 2.8; 95% CI 1.7-4.6; P<0.001). Incidence rate ratios increased with age to 2 to 4years (the ages with highest incidences) then progressively declined with each additional year of age. Further research is needed to define why there is a positive association between BCS and rate of urethral obstruction. In the interim, clinicians should encourage owners of castrated male pet cats to ensure their cat's BCS is not high.
