3. Stool Problems
When cats start acting strange, it is always important to check the litter box. If there are any problems with constipation, diarrhea, or even bloody stools; contact your vetenarian right away to ensure it is just stress.
Cats are independent creatures, almost always hiding throughout the day and come out at night to play. However, when they don’t feel well they tend to sleep more and isolate themselves from everyone. If you believe this is more than stress, consult your local vet.
