Objective To study the growth and development patterns of British-shorthair Cats in the

laboratory. Method Determine the growth performance indicators of laboratory cats aged 0 - 24 weeks, including body weight, average daily gain, daily food intake, and daily water intake. Result the body weight of males was higher than that of females at the same age group, with significant differences ( P< 0. 05) between 10 weeks old, 12 - 14 weeks old, 16 weeks old, 19 - 21 weeks old, and no significant differences in other stages; The weight growth rate of laboratory cats at different growth stages is not stable, and the average daily weight gain changes significantly. However, compared with different genders, the difference between the two is not significant in most growth stages, only 5-6 weeks old and 18-19 weeks old. The average daily weight gain of males is significantly higher than that of females (P< 0. 05) . At the age of 0-24 weeks, the daily average feed intake of males was higher than that of females, with significant differences ( P < 0. 05) among the ages of 11 - 12 weeks, 12 - 13 weeks, and 18 - 19 weeks, while no significant differences were observed among other ages. Comparing the daily average water consumption among different genders at the same age group, females aged 11 - 12 weeks were significantly higher than males (P<0. 01) , males aged 12-13 weeks and 17-18 weeks were significantly higher than females ( P < 0. 05) , males aged 19 - 20 weeks were significantly higher than females ( P < 0. 01) , and males in other growth stages were also higher than females, but the difference was not significant. Conclusion The weight of British-shorthair cats aged 0-24 weeks in the laboratory increases with age, and during this period, the weight of males at the same growth stage is consistently higher than that of females. After 12 weeks, there is a significant weight difference between males and females. The turning point of weight gain for male kittens is between 18-19 weeks of age, while for females it is around 21- 22 weeks of age; male kittens have stronger resistance to stress during weaning and separation compared to female cats.
