9. Be aware of bladder problems
If you keep them nice and clean, cats will always use a litter box. Should your cat al of a sudden stop using the litter box and you see that they’ve begun to go to the bathroom outside the box (when litter is clean) and/or have blood in their pee, then these may be the signs of a bladder infection or urinary tract infection. Go to the vet asap as urinary tract disease in cats can be painful and if left untreated, can be fatal.
