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!

Hello, my name is Dr. Elizabeth and I am happy to help. That bump could be many things ranging from an infected hair follicle to the beginning of an autoimmune condition called an eosinophilic ulcer. If it doesn't seem to be painful, and if Luna is acting normal and eating well, you may monitor the bump for the next 5-7 days and see how it does. At home you want to protect the area from rubbing or scratching and Luna may need to wear an elizabethan collar. If she tolerates it, you can apply a warm (not hot) compress for 10 minutes a few times a day. If this is an infection, it may help it come to a head. Keep the area clean and dry. Have Luna examined if: The bump continues to get bigger. The area is painful. Luna is not acting normal. Luna is not eating well. If it's still there in a week. If you see anything else that is worrisome. Piece of mind is always worth a vet visit. I hope this helps and please feel free to reach out any time.

Thanks for using Petco Pet Education Center, formerly Petcoach! These types of lesions are usually due to allergies or something called eosiophilic granulomas. The cause is unknown though most of the time it is triggered by things like allergies. To effectively treat it you have to get to the bottom of the inciting cause but most of the time steroids are used. There are other possible diseases that can look like that like potentially just mild mucositis or inflammation of the lip. I advise you have her evaluated by her veterinarian to check for an examination and further diagnostics as indicated based on his examination. Further treatment is going to be dependent on what is found. Good luck!

Your cat may have what is referred to as cat acne. It appears often on the lower lip or chin and may develop a pustule. An allergy to plastic is one possible cause, so if she is eating out of plastic dishes, substitute glass, ceramic, or steel bowls and see if that helps. To help heal the bump she has now, clean it twice daily with a cotton ball moistened with hydrogen peroxide or, if you have any benzoyl peroxide acne pads, clean her chin with one of those. If the bump does not improve in the next couople of days or gets worse, starts to bleed, if you cat displays any other symptoms of not feeling well, get her in to see your vet as there may be a more serious underlying problem causing her symptoms.

This small pimple type spot could be from an injury (such as scratching her chin), an infection, or chin acne. I would gently clean the area with warm water and antiseptic soap, and keep an eye on it for now. If it doesn't go away, it gets bigger, more of them appear, or you see redness, swelling, or pus in the area then I would take Crystal into the vet to have the area looked at and treated. Good luck, I hope this helps!
