Is my Kittie in those days?

It may be time for a vet visit, especially to check her teeth. If she's refusing anything but canned food it might be a sign of tooth or dental problems. A vet can also give you a better idea on her age, and if she is nearing time to go into heat. You should get her spayed when it is safe, but the meowing a cat does when she is in heat is usually quite different than normal meowing, as anyone who has lived through it may attest.

Welcome to Pet Talk! This is a great place for learning and encouragement.

I concur w/Karen: a vet visit is in order. It sounds as though she could be having dental issues and it's important to have a vet check it out b/c bad teeth can cause other health problems as well. Getting her spayed is vital, not just b/c she could get pregnant (hopefully, you've made her an indoor cat; much safer) but it can help to prevent uterine cancer.

Give your kitty some scritchies for me and please update us soon.

My son's cat was very small, just about 3 lbs, despite being 6 months old. Luckily he recognized it when she went in heat and was able to keep her in until we could get her to the vet.
Good luck.
