Help Oreo get to the proper care he needs!

Hi thank you for checking out this gofundme, this is my 15 year old cat Oreo! Recently a growth was found in his ear, and at this moment in time its unknown if it's cancerous or not. Currently money is tight and even getting him a check up to see if it's cancerous or not is hard to do. If you could spare some money it'd be helping him get the proper care he needs and deserves. I don't want my little guy to be in any pain so anything helps. As of this moment I don't have a picture of the growth itself, but I will add it once I get a proper picture. He's had a long history of having problems with his ears so if anything else is found besides the growth it will go to that too. Thank you so much for reading, again anything helps!
