Fever?

[moosmom]

Another thing you can look for is the "third" eyelid. If it is present, chances are the kitty is sick and needs to see a vet.

The third eyelid is white and in the corner of the cat's eye where the tearduct is.

I also got a digital thermometer. Ever try and hold a cat still while sticking a thermometer up it's butt???
