They can just be soooo moody sometimes it's hard to tell if you should be worried!! I think all the advice above is great. I would say if she continues this for a few more days that it won't hurt to have the vet check her.

I knew something was wrong but convinced myself that I was an over protective, paranoid meowmie! I wish I had followed my instincts!!
