The weakness of the cat's limbs, like being drunk, should be caused by diseases, such as infectious peritonitis, kidney failure, etc. It is best to take the cat to the hospital for examination to avoid delaying the treatment period. At ordinary times, you should pay attention to supplementing the cat's nutrition, do not let the cat go outside to contact other unhealthy cats, disinfect the environment regularly, and if possible, take the cat for regular physical examinations.
