Analysis of Breeding and Application Data for Laboratory Cats

Objective To cultivate and breed laboratory cats in conventional laboratory animal facilities, collect background data on laboratory cats, and compare them with purchased domestic cats to assess the feasibility of breeding laboratory cats. Methods Indigenous cat breeds were introduced for reproduction and population expansion under conventional laboratory environment, with recording of kitten survival rates and growth curves. Indicators of 20 laboratory cats of F1 generation (half male and half female), including complete blood count, blood biochemistry, organ mass, organ coefficient, heart rate, and blood pressure, were detected and comparisons between sexes were made. Blood pressure values and sensitivity to histamine of these cats were measured using depressor substance detection method in the Pharmacopoeia of the People's Republic of China-Four Parts: 2020, and were compared with the data from 173 concurrently purchased domestic cats. Results Laboratory cats adapted well to the environment of conventional
