It can be tough to notice the subtle changes in your cat that may indicate something is wrong. Cats are very good at hiding their ailments to even the best of owners.
Here are some signs to look out for:
1.Changes in appetite (eating more OR less)
2.Stinky breath
3.Eliminating outside the litter box
4.Weight change
5.Behavior change
6.Grooming change (Grooming too much or too little)
7.Activity change
8.Sleep pattern change
9.Voice change.
All these are reasons to take your cat to your veterinarian.
