Hey Kim
My cat does the same thing n' she just started it not to long ago either. My Mom's best friend is a vet. I asked her about it.....she said that it was just nerves....although she doesn't have a rash either. I noctie she mainly does it when a lot of different people may be around....cause she is not the social type. Plus my Mom seems to think it might be her age....cause my babys getting old
She does it at..the back of her front lefs, belly, n' the bottom of her tail. Here is a picture of her legs....

People have told me to use Gold Bond n' that didn't work.. I didn't want to use Bitter Apple....I was afraid it might irritate her skin more than it already was. Im goin to try something new now.....my Mom ordered some Avon Oils or something like that n' we were goin to rub it on our hands then on her skin were it is irritated. I'll tell you how it works.
