What to do if my cat's tail is limp, swollen, and painful?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | neutered | 14 lbs

Hi, my cats tail is limp and looks a little swollen at the base, he doesn’t seem in pain he is still purring as usual but he is moving slower than normal, he hissed quite aggressively when I touched it (not normal) he usually lifts his behind and raises his tail when clapped but not today, he is trying to and is moving it more as the day goes on but it is not straight up as usual or anywhere close to normal, he is a night cat and fights a lot, could he have been bitten maybe?

This appears to be a classic presentation of a tail-pull injury. This happens when the tail gets pulled very forcefully (either it gets stuck under something like a car tire, or gets pulled by someone). This causes significant damage to the major nerves at the base of the tail, which is very painful and can cause paralysis of the tail. This requires that you take Kovu to a vet as soon as possible. It's not an emergency, but best if you go to a vet within 24 hours, because he will need pain medication and possibly other treatment. Your vet will be able to give you a better idea about the severity of the injury and prognosis. I hope that helps and Kovu gets better soon.

    Poor Kovu! If he is allowed outside, he could have injured his back or tail causing these problem. If he's not lifting his tail in the air, he is aggressive to you when you try to touch it, and he is not walking well, then yes he is in a lot of pain. He needs to see a vet now for this, as there isn't anything you can do at home for his pain. Many human pain medications are toxic to cats and are fatal if given, so the only safe pain meds are available at the vet. He should also have x-rays done on his back and tail to see what is causing his pain. Please take him into a vet now. I hope this helps!

    Poor Bo is in pain. He may have injured it outside. I recommend resting him for the next 48 hours. No running, jumping, or playing. Take him out to toilet on a leash, and bring him right back in when he's done. If he still appears painful after this time, then I would take him into the vet for an exam. The vet can diagnose where the pain is coming from, and can dictate a treatment plan for it. He may also benefit from some pain medications, which the vet can prescribe. Please do not give him any human pain medications, as many are toxic to dogs and can be fatal if given.
