Signs of a Healthy Cat

1) Healthy overall demeanor

The following are signs of a healthy, happy kitty:

2) Healthy digestive system

A healthy kitty's poops will be "normal" (for want of a better expression!) Diarrhea or constipation either indicate a health problem or a diet problem.

3) Healthy skin and fur

Healthy skin is supple, smooth, dandruff-free and free of spots, scabs etc. Healthy fur is shiny, sleek and free of tangles.

4) Healthy teeth and gums

Healthy teeth are white (though they may yellow a bit as your cat ages), and they're tartar-free. Healthy gums are pink (not red), don't bleed and are tartar-free.

5) Healthy bones and joints

A cat with healthy bones and joints will have a good posture and will be able to do all the normal kitty activities such as climbing, jumping etc.

6) Healthy body size and shape

Healthy cats aren't too fat or too thin. You should be able to feel Kitty's ribs, but not see them. Also, when you look at him from above, you should be able to see a waistline below his ribs.

If your kitty is long haired, you may not be able to see his waistline, but you should be able to feel it.
