My cat has a red bump on her rear. When should I take her to the vet?

Poor guy. The fact that he is so young, and the location of the bump, suggests that he may have unfortunately been bitten by an insect in this area. If he is not licking it excessively causing redness of the skin or seems bothered by it, I would leave it be for now and monitor it for the next few days to see if it starts to resolve on its own. If it seems irritating, then you can try applying a very small amount of Neosporin on the area and play with him for 15 mins to allow it time to absorb. Do not apply too much where he can lick it off and cause stomach upset. If it happens to not be improving after 4-7 days, then I would take him in to your vet to have him checked out so they can get a closer look at the area. Other possible causes is a foreign body with subsequent inflammation (granuloma) or an allergic skin reaction. I hope everything goes well for your little fur baby Cleo moving forward. : ) Best wishes and take care!

Thanks for using Petco Pet Education Center, formerly Petcoach! It is not possible to diagnose this based on a picture. Possibilities include inflammatory disease, cancer, immune mediated disease, an infection, among other possibilities. I recommend that you have her evaluated by a veterinarian for further assessment and treatment. They may have to take samples from the lesions to try to find out. They Good luck and have a great day!

Hello, and thank you for your question. Reddish bumps on his anus could be a tumour, a polyp or wart, or a partial rectal prolapse. It is impossible to say for sure without seeing it directly, so I would recommend getting Simba seen by the vet within the next few days, or earlier if he seems in discomfort. They may be able to determine the cause just by observation alone, or may recommend a fine needle aspirate to pinpoint the nature of the mass. In the meantime, if he is licking or biting the bum area, I would suggest putting an e-collar (cone) on his head to prevent further trauma. I hope this helps, and that your little stray cat gets better soon!

Thank you for attaching a picture of Leo's bump! It could be from an injury, such as him scratching his chin and accidentally cutting himself. I would keep an eye on it for now. If it doesn't go away in the next few days, gets bigger, there is pus from the area, and/or it starts to bother him, take him into the vet. Best of luck.

It is difficult to diagnose without seeing the bump but it could be an infection, cyst, mass, or an injury. The best thing would be to have your vet take a look at it to determine the exact cause and best way to treat. He may need an antibiotic, anti-inflammatory, or other medications to treat. Your vet can do a needle aspirate, if necessary, to help diagnose the cause of the bump.

The pictures are not clear but this must be checked by a vet urgently. I would be concerned that this is a prolapse (when internal organs poke out) and surgical repair may be required, urgent assessment is vital as damage and trauma can occur

Hello there, Thanks for the good photo. If it is a small minor wound like a pimple or scratch, it should be mostly healed within a week of forming. If its been present for longer than that or is worsening, I would be more concerned that it is the start of an infection or growth that would benefit from being seen by her veterinarian. I hope this helps. Thanks for using Petco Pet Education Center, formerly Petcoach.
