Medication can also be given to control the diarrhea. Your veterinarian may also prescribe a special, bland, easily digestible, high protein veterinary diet tailored for cats with intestinal upset.
If astroviral infection is suspected in your cat, then you will need to keep your cat away from all other cats until the infected cat no longer has diarrhea or is displaying any other symptoms.
