Suddenly I found that my cat was walking unsteadily and losing balance. The possible reasons are as follows: 1. Unsteady walking caused by lack of vitamin B1 and calcium mostly occurs in young cats. The owner only needs to supplement the cat on time; 2. . If you lose control of your hands and feet due to cold and fever, you can take cold and anti-fever drugs; 3. If you have a head injury while playing, it is recommended to seek medical attention.
