My cat has had a small pimple thing on his neck for months. It’s been popped twice, he doesn’t seem to mind it, but it came back both times. What the heck is it?

Of course a biopsy is needed for definitive diagnosis, but I suspect by the picture and what you describe that it may be a sebaceous (oil) gland cyst. They will not go completely away, but are usually pretty quiet and don’t cause problems. To be safe I would recommend having it examined by a veterinarian. Good luck to you and Willard.
