My cat has a blister-like sore on her lip. Should I be concerned?

I am very sorry that Kitty has his sore near her lip. Thank you for proving pictures, it is difficult to know precisely what caused this lesion it may have been a cat scratch, a traumatic puncture from for example a fence, or possible a primary skin like feline acne, or allergic disease. At this stage it appears to be slightly crusted and inflamed and I would suggest a trip to the veterinarian. The vet will most likely clean the wound and debris any necrotic material. The vet may also send home pain relief, anti inflammatory medications and / or antibiotics. The vet will also be able examine the area and reach a diagnosis. Best of luck to you both and thank you for using Petco Pet Education Center, formerly Petcoach.

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concerns about Buttercup! Based on the photo you provided, it appears as though what is shown in the video could be blisters or cysts that have developed on the chin region. I would recommend applying a warm water washcloth to the area 2-3 times daily and consider applying a veterinary product with benzoyl peroxide in it. I would also consider having a veterinarian take a look at the area as an in person evaluation would give you more of an answer. The veterinarian can take a small needle and see if any contents can be expressed from the area to confirm if it is a cyst or not. I hope this helps guide you in the right direction!

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. From the blurry picture, it is tough to say for sure what this is but it looks as though there is a ulcerated sore on the upper right lip. This looks as though it could be consistent with an indolent ulcer, which is part of a disease known as Eosinophilic Granuloma Complex (EGC). The cause of EGC is typically unknown but treatment is generally steroid therapy (topical and systemic). Generally, an antibiotic and anti-inflammatory are used to treat these. Also, if Leo is drinking / eating out of plastic bowls, switch to metal or ceramic to see if this helps. Many times, these lesions pop up for no known reason and go away after treatment. These lesions may not show up for months to years later once initially resolved. If this sore is not improving, I would have a veterinarian take a look at it so that the most appropriate diagnostic and treatment recommendations can be made. I hope this helps!

I suspect he may be developing an ulcer due to allergy or eosinophilic granuloma complex. If the lesion is getting worse I would advise getting it examined by a vet asap as without prompt treatment these issues can become quite severe.

Hi Gabriela! I'm glad to hear that Marvin seems to be normal aside from the lesion on his lip. From the pictures, this lesion looks most suspicious for an indolent ("rodent") ulcer, which is related to a complex of eosinophilic diseases. These conditions can be related to underlying allergies or a genetic predisposition to these lesions. I do recommend taking Marvin to his vet sometime this week because he may need a course of steroids to help this lesion to improve, but this is not an emergency condition. I hope this helps and that all goes well!

Hi there, This appears very similar to something called a "rodent ulcer" or Eosinophilic Granuloma Complex, but it may be something different, like an infection or a growth. Eosinophilic granulomas are often thought to stem from an overreactive immune system or allergies to insects, a protein in their food, or their environment. Many cases resolve with a course of medication. Some cats need to have strict flea control or a prescription diet. Your vet can tell you more about Chibi's specific case after they do a physical exam. Just in case it is an Eosinophilic Granuloma, here is a link to learn more: https://vcahospitals.com/know-your-pet/feline-eosinophilic-granuloma-complex-in-cats I hope this helps!

The pictures attached this time! That sore on Bear's lip looks pretty red and sore. I would be concerned that it could possibly be infected. Likely it's hard to get that to heal given he will probably be licking it with his tongue a lot since it will bother him. I would have him seen by a vet. He will need oral antibiotics if there is an infection to help the sore heal correctly. I hope this helps!
