My cat has a hard lump on his belly after squeezing out black stuff.

Pet's info: Cat | Mixed Breed | Male | neutered | 10 lbs

My male cat has 2 small lumps on his belly that I was able to squeeze and get a firm blackhead-like substance. Once that was removed I noticed there was still a hard mass underneath that I couldn't remove. So there is still a lump but it seems to be not removed. What could this be?

There is no way to know what this mass is without seeing your cat. It could be a benign or cancerous tumor, or firm ball of scar tissue, or an abscess. I recommend a visit to your vet for a fine needle aspirate and cytology, where he/she will take a sample from the mass to examine under a microscope to give you a diagnosis and come up with a treatment plan.
