Hard Lump in a Cat’s Tail

Your cat expresses his emotions through his tail. Just by looking at that appendage, you know if he’s happy, annoyed, or frightened. While the tail might not receive a lot of petting, it’s important that you check it as you would the rest of your cat’s body for lumps, bumps, or other abnormalities. If you find a hard lump on your cat’s tail, take him to the vet.

Hard Lump in a My Cat Tail
Said Dr. Hanen Abdel Rahman Have your cat’s vet take a look before concluding that you have to remove the lump. This could be a cat-bite abscess, given the fact that the other cat frequently bites Gracie on the tail. It could also be a lipoma; a benign lump of fatty tissue.

Are tumors in cats hard or soft in Tail
Lipomas are benign (noncancerous) fat-filled tumors. They are soft, relatively slow-growing, freely movable (i.e., easily manipulated), and located just under your cat’s skin (subcutaneous). While they can develop anywhere, they are most commonly found on your cat’s undercarriage, in the chest or abdomen.

Broken Tail
A lump in your cat’s tail, especially near the tip, can mean that he broke it at one time. While you’d likely be aware of such an incident in a pet you had since kittenhood, that might not be the case in a cat who came into your life when full-grown. There’s no real treatment for minor tail fractures — they heal on their own. The lump that exists after a fracture could have resulted because the cat continued to move his tail during the healing process.

Tail Tumor
A hard lump on the tail could be a tumor, either benign or malignant. Your vet can’t tell whether or not a tumor is potentially deadly just by looking at it, so she’ll either remove the entire tumor if it’s small or takes a sample from a larger tumor and send specimens for testing. Samples from a large tumor are usually retrieved via fine needle aspiration, which doesn’t require anesthesia. If the tumor is benign, no more treatment is necessary, unless it’s a sebaceous cyst. That’s an encapsulated tumor filled with sebum, which your vet can surgically remove. If a tail tumor does turn out to be cancer, your vet might recommend tail amputation.

Tail Abscess
A large, painful swelling on your cat’s tail could indicate an abscess. Outdoor cats are most likely to suffer from tail abscesses since most abscesses result from fighting. The tail area is a common site for bites, as the dominant cat might inflict a bite as the other cat flees. Bacteria from the bite cause the site to fill with pus. Within a few days, you’ll notice hair loss around the swelling. If your cat hasn’t already gone to the vet to have the abscess lanced, it could break at home. It’s amazing how much pus and blood can come out of one feline abscess. In addition to lancing the abscess and cleaning it, your vet will prescribe antibiotics to combat infection. Large abscesses might require a drain.

Stud Tail
Although tom cats primarily develop stud tail — hence the name — neutered males and females can come down with this malady. Technically known as supracaudal gland hyperplasia, stud tail symptoms include a mass of hair at the tail’s base, which can feel like a lump. The area is smelly, oily, crusty, and possibly infected. Your vet will clip off the matted hair and recommend degreasing shampoo to get rid of the excess oil, caused by sebaceous gland overactivity. If an infection exists, she might prescribe antibiotics. If your cat isn’t neutered, your vet will recommend that surgery.
