Did a reverse image search on this picture and found a Reddit thread from 3 days ago where experienced vets said it’s Malenoma that can be cancerous & eye removal is needed. This is the other picture provided, but I just wanted to say what is wrong with people? there is so many rude comments here that are not helpful. There wasn’t a single rude comment on Reddit, simply people trying to help. & posts like this bring awareness to people who have not encountered these issues!!

You can vet send picture and theyll let you know if serious or not… vet might be better answer then strangers

I would strongly encourage a visit to the vet. Some offices are very kind and will allow you to email a photo and ask questions in that message to see if coming in for testing & evaluation is needed. I’d be concerned about possible melanoma. Definitely reach out to your kitty’s GP and go from there! Hope all is well!

I’d ask people for help too before going to the vet they charge an arm and a leg for just stepping in the door I swear😩jojo but obviously she will take the cat to the vet but why not ask for some help before that??
