Hey! So my cat, she's a year old, and she gets these bumps around her mouth and loses fur in patches around her mouth as well. I've attached a few photos. Thank you for your advice in advance.

Hi and thanks for using Petco Pet Education Center, formerly Petcoach! Sorry to see that Nitro is having these problems. These areas of concern could be due to allergies, immune system mediated, or contact with irritants. There is a syndrome in cats called Eosinophilic Granuloma Complex that is an immune mediated problem thought to be caused by allergies, most times to the bite of fleas, mites, etc. Only a biopsy would be able to adequately diagnose these areas. Food allergies/food insensitivities may also be involved. Looks like something you should let your vet take a look at. Most likely they would use a steroid injection with or without antibiotics. These can be complex to figure out but some tests can be done and a treatment plan can be formulated. Plastic feeding and water bowls have always been implicated as possible sources of the irritated areas so you should switch to porcelain or glass bowls. I hope this helps and I hope you and your vet can make Nitro more comfortable.

Poor Liliana! It looks like she may have eosinophilic granuloma complex with a rodent ulcer on her upper lip. With This and her excessive itchiness, she may be best off with a long acting steroid shot. Unfortunately this isn’t a cure, but it will make her more comfortable. She will likely need steroid shots through the year for the rest of her life to keep This under control. I would also talk to your vet about a hypoallergenic diet as This can sometimes help control the symptoms long term. In the meantime you can try some Benadryl twice a day and feeding canned food to keep her comfortable. See link below. I hope this helps. https://www.petcoach.co/canigive/cat/benadryl/
