lAli's mom, welcome to Pet Talk.

It sounds to me that she is walking in something that is making her pads rough. It comes to mind that perhaps a floor cleaner that is being used, sharp rocks or sand, is where she likes to go, could be the answer. Possibly even her kitty litter could be the problem. Also, is she an indoor or outdoor cat? This could make a difference.

I have generally found that a cat will lick off any type of creme or whatever can be used to treat the symptom, therefore, I suggest that perhaps is would be best to locate what is making her paws so rough.
