Pet's info: Cat | Maine Coon | Male | neutered | 16 years and 1 month old | 16 lbs

Hello, I have a 16 year old maine coon who is slightly overweight and has spent his life as an indoor cat. I recently noticed a small bump on the back of his neck and the hair around it was somewhat oily, as if it had been leaking some type of fluid. It is red and raw looking. He is not behaving differently still eats/drinks/sleeps like normal and it does not appear to be painful to him when i touch it. As long as i have had him he has had moles but not so raw. What could this be?

This could be a cyst, a benign tumor, or a malignant tumor. Any suspicious lumps should be examined by the vet. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the lump to get a sample of its cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. Once the cause of the lump is diagnosed, the vet can discuss treatment options if needed. I would give Stanley's vet a call to make him an appointment. Best of luck.
