Cold paws do not necessarily mean a cat is sick. Normally, the temperature of a cat's paws should be room temperature or warm. If it is a relatively hot summer, the cat will dissipate heat through the paws, and the temperature of the paws will be cooler at this time. But if there is no heat dissipation or the temperature is very cold, then it may be sick. It is best to take the cat to the pet hospital for examination to avoid delaying the condition.
