cat got big blister on her lip, help!!

please can someone help, i have just noticed my 1 yr old has has a large what looks like a blister on her lip, it looks sore but does not seem to bother her to much, she is still eating well (even tho i susspect she is about 3 weeks pregnent!) does anyone have any ideas?? thank you x

you could try taking her to the vets to see what they say

Your kitty needs a vet visit. It could be rodent ulcer which are painful and itchy to you cat. They hide discomfort very well.

Willing to bet its a rodent ulcer (which does look like a blister). Have her checked by your vet ASAP so it can be cleared up with meds.

My last cat Max got something like that, which turned out to be an allergy to plastic(!). In any case, she needs to be seen by a vet to know for sure, and to be properly treated for whatever it is. Good luck!
