Thanks for the response. It's on the underside and she's an outside cat. The more I look at it, it looks like a scab. I'll monitor it daily and if it gets worse I'll take her to the vet.
I noticed it the other day. Any ideas what it is? Any antidotes? She's not picking at it and she seems perfectly normal otherwise. it's hard crusted and not wet and seeping.
Thanks.
