I'm sorry, but kitty needs to see a vet. I'm sorry that you can't afford one, but if she is not eating, something is wrong. Can you call the humane organizations in your area and find out if there is any ability to have her checked there?
Good luck. If worst comes to worst, you might consider surrendering your cat to a no-kill shelter. At least they will have access to a vet.
Hello. How is your kitty tonight? Were you able to get her to the Humane Society or a similar organization?
My cat is eating again. What ever it was she recovered on her own. She woke me up at 5am hungry and has been eating normal ever since. First small but working her way up. I am keeping an eye on her.
