If you can, you can take your kittens temperature with a ((rear end)) thermometer. Usually cats and dogs will have a higher temp than us normally. Around 102 or so. But the best thing that you can always do is take her to the Vet. She might have a resp. Infection or even possibly a virus that needs to be put under control.

 The temperature could have something to do with it, or your cat may very well have a fever. Visit the vet as soon as possible.
