My cat has a hard lump on her chin. Is it a bug bite or growth?

Updated on September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | unspayed | 1 year and 2 months old | 6.5 lbs

I noticed a lump on her chin when I was flea combing her. Don't remember it being there yesterday...or even last night, but not 100%. It's hard, like a pimple or mosquito bite. I only use metal and ceramic bowls. Is it probably a bugbite?

This could be a bug bite or a small growth. If it is not painful and not getting bigger then I would watch it and have her seen by your vet if it doesn’t go away in a few days. Sometimes I need to poke a growth with a needle and look at it under the microscope to determine the cause. This is not necessarily an emergency but should be seen and worked up if it doesn’t go away in a few days or gets bigger. Watch for discharge from swelling, change in appetite or energy level.

Thanks for using Petco Pet Education Center, formerly Petcoach! While this may not be an emergency, I do think that it warrants a visit to your veterinarian for further assessment. This could be a benign or malignant growth. This is often differentiated by a test called a fine needle aspirate (FNA) which is a pain free, inexpensive and easy procedure which in most cases will help reach a diagnosis. Sometimes a biopsy is needed for a definitive diagnosis. I recommend that you have him evaluated by your veterinarian for further assessment and treatment. I am really hoping for something benign. Good luck and have a good day!

My cat has a red bump on her chin. Is it a tick, bite, or infection?

This looks like a small, localized spot of infection, sometimes referred to as a hot spot. If the infection is contained to this one area you can try to treat it at home with some topical antibiotic ointment (like Neosporin). If this does not take care of the problem, or if there are other areas like this on her skin, I would recommend having her checked out by your vet so a systemic antibiotic can be given.

My cat has a red lump and bald patch after a bug bite. Vet needed?

I would definitely take him to the vet to have this checked. From what you say I wonder if this is a tissue reaction to a little piece of the bug left behind. It looks more like reaction and infection than a tumour, but that is always a possibility. I wouldn't let that put you off, head to the vet and see what they think.

What is this growing lump on my cat's face and is it serious?

This may be an abscess, a cyst or a tumor. You should have it examined by your veterinarian, as it is not possible to distinguish these by just looking at a photo. An abscess can usually be treated with antibiotics and/or be lanced, and a cyst can be evacuated. To identify a tumor, your vet may want to do a fine needle aspirate (he takes some material from the bump with a needle and then looks at it under the microscope) to determine whether the mass is concerning.

My cat has a new black bump on her chin. Could it be feline acne?

This looks like it could be a scab or potentially feline acne. Feline acne can be related to using a plastic or dirty food bowl so you may want to switch to glass or ceramic if you have a plastic bowl. It does not typically require treatment and does not bother the cat. If this lesion is getting bigger, if you notice redness or discharge or if it seems to be bothering Lydia I would recommend having your vet examine it.

My cat has a bump on her lip that doesn't hurt. Should I see a vet?

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. Based on the pictures you provided, I would recommend just monitoring this for the time being. It could be an area swollen from her hitting her chin on something or it could be an infection / pimple (acne). If it does not resolve on its own, I would recommend having Mouse examined by a veterinarian so that the most appropriate diagnostic and treatment recommendations can be made. I hope this helps! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.

My cat has a recurring black lumpy scab on her chin. What is it?

This lump/growth should be ideally examined by your veterinarian to have a definitive diagnosis. Your vet will examine it and possibly perform with an FNA (fine needle aspiration) or a biopsy. Differentials would include skin cyst, infections or benign or malignant type of tumors. Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.
