2 days ago i noticed a big black scab on my cats chin, i am familiar with cat-ne (feline acne) and i have not noticed it on him previously. The scab was pretty large and when i looked at it today, he allowed me to touch it so im assuming it isnt causing him pain and it kinda just fell right off. However, now there is a big raw spot where the scab was. Its rather pink and i think i saw some clear and possibly some yellow fluid coming out of a couple spots. But at this point, he was uncomfortable and ran away so i couldnt get a better look. Anyone have any ideas? It just seemed like too big a scab to be acne..
