Since cats can’t (or won’t) talk, they can’t tell you when they’re feeling sick. That’s why you need to watch your cat carefully and look for signs that your cat may be ill. One simple way is to watch if your cat suddenly stops using the litter box and uses anything but the litter box.

Also look for changes in behavior such as sudden aggressiveness or shyness. Whenever your cat’s behavior changes drastically, that’s a sign something may have changed in your cat’s life and that change may be due to physical illness, so study your cat carefully and get it help as soon as possible.
