Thanks for the suggestions.
It probably is fleas and/or mites. We live in Puerto Rico and there is a huge problem with fleas here. I have used cat flea powder on her but think I will try dog powder instead. We can't afford any of the expensive brands since we have 25 cats. We started out with 3 and have adopted lots of others than have been abandoned and we found.
I do have a vet that I am doing a website for. I will take her there but can't do it for about 2 weeks since it is across the island. The posts help. At least I know of some things I can do until I can get here there.
Thanks again for all of your suggestions.
