My cat has a hard bump on its chin. What is it and should I worry?

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's hard to see what is going on from the photo. Bumps on the lips/chin can be a number of things, including feline acne, infections under the skin, allergies, etc. If Leo has trouble getting to the vet, I would definitely look into the sedative option, or see if there is a house call service near you that can come to you. Both of these options are a great way to make veterinary care a little easier. Since bumps on the chin may require having a sample taken of them to determine it's cause, sedatives may be needed regardless to ensure everyone is safe and calm during the procedure. Until you can get to the vet, I would continue to monitor the area for additional changes, keep it clean and dry, and if it is itchy or bothersome, place an Elizabethan (cone) collar on Leo to keep her from rubbing the spot which can lead to more irritation. If she's wary of the carrier, working on getting her used to it by leaving it out at all times and tossing treats in it/feeding her next to it may help make it a little easier if you do need to use it.

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! This could be due to an abscess for example. I recommend that you have Leo evaluated by your veterinarian for further assessment and treatment. If this is confirmed, your veterinarian may recommend drainage and further local therapy as well as antibiotics. Good luck!

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. Please take the time to mark this question as helpful or not as it helps us to improve on the quality of our answers to other pet owners. Thank you kindly!

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.

This is likely a small bug bite or an inflammatory reaction to some type of trauma (puncture, scratch, abrasion) to the skin. You can try cleaning it with a small amount of Betadine diluted 50:50with warm water, letting it air dry, and then applying a thin layer of Neosporin to the area twice a day to see if this can start to heal over the next few days.. Also an e-collar purchased from your local pet store can be placed on Simba to prevent her from scratching this area and causing more irritation as well as delaying the healing process. If this doesn't help then its best to see your vet to have this area investigated closely and in person. The vet may also want to shave the hair around it to get a better view and prescribe topical pet friendly antibiotics to help this heal. Best wishes with your kitty Simba and I hope this wound resolves soon. Take care.
