Abstract
ObjectivesProspectively collected data were used to estimate the prevalence of gingivitis in a cohort of companion cats aged up to 6 years and to investigate factors associated with the risk of gingivitis in cats aged 3 to 4 years.Materials and MethodsData were obtained from a longitudinal study of domestic cats (the Bristol Cats Study), using owner‐completed questionnaires and veterinary surgeon‐completed oral health scores. Prevalence estimates of veterinary‐reported gingivitis for cats aged up to 6 years old (n = 1534) were calculated for different age groups. Cat signalment, diet and dental care were assessed for association with gingivitis in cats aged 3 to 4 years (n = 317) using univariable and multiple logistic regression.ResultsThe prevalence of gingivitis increased with age and ranged from 24.5% (<12 months old) to 56.3% (5 to 6 years old). Odds of gingivitis in cats aged 3 to 4 years were higher in cats fed a wet only or mixed wet/dry diet compared to dry only (odds ratio: 2.7; 95% confidence interval: 1.4 to 5.1), cats not reported to hunt compared to reported hunters (odds ratio: 2.1; 95% confidence interval: 1.0 to 4.2), cats reported to dribble whilst being stroked at age 6 months compared to reported non‐dribblers (odds ratio: 3.2; 95% confidence interval: 1.3 to 8.4) and cats with orange variants in their coat colour compared to non‐orange cats (odds ratio: 2.3; 95% confidence interval: 1.0 to 5.3).Clinical SignificanceThese results will help veterinary surgeons identify cats that may be at a greater risk of gingivitis and provide an evidence base to inform dietary and oral healthcare recommendations aimed at promoting gingival health in cats.
