I would start with some simple investigation at home. First, examine the skin and fur over and around the lump - is there redness, a watery or snotty-looking discharge, a loss of fur? These would be indications of infection, which should be looked at by a veterinarian since the meninges of the spinal cord do extend into the tail for some way. Second, see how the cat is holding the tail - is there evidence of pain (you can try gently applying pressure, but be wary because you may get a handful of claws if it really hurts), a change in how the tail is positioned? This may indicate a bony injury, which may benefit from some pain medication but otherwise should heal on its own. Third, does it look like the lump is new, or could it have been there for a while and you simply didn't notice it? An old injury, or a slowly growing tumor (rare, but possible), may be the cause.
Provided there are no signs of infection, you can probably wait this one out a few days and see what happens. If it gets worse, or you are worried about cancer, make an appointment with your veterinarian.
A tumor, go to the vet.
Part your cat's fur at the lump and try to identify if the lump is part of the cat, or something on it. If it is not part of the cat, try to identify what it is. If it is a burr, remove it gently with your hands or a brush. If it is a tick, grab the tick's body and SLOWLY pull it off.
You do not say if this is a cat, dog, horse or what kind of animal. Best thing to do, is to take your pet into your Veterinarian and have the lump checked out. It could be a cyst, cancer, abscess, etc. etc.
The soft, movable lump on your cat's back next to the tail could potentially be a harmless fatty mass known as a lipoma. However, it's essential to have a veterinarian examine it to rule out any other potential causes, such as an abscess, cyst, or tumor. Regular check-ups can help monitor the lump and ensure your cat's health.
The possessive form is 'the cat's tail'.
The big lump a the end of your ferrets tail is called a chordoma and will need to be surgically removed because it is cancerous. Contact your veterinarian for advice.
its tail should look like a big lump of cotton
Cats show emotion with their tail. Every cat is different. My cat responds to me with her tail when I talk to her. Only you can tell if your cat is mad or angry when she moves her tail.
If a cat's tail comes off the cat should see a vet. It is important to make sure that the cat does not have an infection.
That means it has no fur on its tail. It is fine. Maybe the cat kept licking its tail until the tail went bald.
A cat's tail can play a role in the cat's balance (though this isn't vital). The cat's tail is also used to show what the cat is feeling. Ever see a cat furiously twitching its tail right before it attacks? That's a good example.
