My cat has a bleeding sore on his lip. Should I take him to the vet?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | neutered | 24 lbs

Should I take my cat to the vet? There’s this sore by his mouth that started bleeding last night. It’s stopped now but his lip still looks a little funky. He’s about 6 years old, definitely overweight but on a diet. The second and third image are from last night and the first is from this morning

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.

    The bleeding has passed and I am sure she is sore from the injury. You can make sure it stays clean and I would recommend taking her to the vet since it is deep. It is a heavy traffic area which can trap dirt and food from grooming and eating and that can lead to an infection. Generally these heal without even knowing it was there

Is this something I should be concerned about? It popped up a few days ago and looks like a scab. We thought he may have just bit his lip where his new teeth are coming in. There is a red spot on the other side as well but no brown spot. He was just
This looks to be a little sore on the lip that was caused by some sort of puncture wound, scratch, etc. I would monitor it for now and perhaps use a daily water additive or oral rinse that you can get from your local pet store. If it has not resolved or worsened after 7-10 days, then its best to take Arlo to your local vet to get this checked out to make sure there isn't something underneath the skin that got stuck and can't come out (foreign body) that has caused this. Also the vet can do a complete oral exam as well to ensure the gums and mouth look ok. I hope that your fur baby gets this to heal well soon and that it is just a sore. Best wishes and take care! : )

My cat has had this for about 1-2 weeks now. I feel like its getting worse and starting to bleed a bit. Does anyone know whats going on? Otherwise he's eating and playing like he normally does.
Thank you for submitting your question regarding Oreo. I recommend that he sees his veterinarian. His upper lip appears very sore. He could have a skin infection or have the beginnings of a disease known as indolent ulcers. This is a serious condition that is typically triggered by an allergy. His veterinarian will examine him and may recommend a skin biopsy. I hope this information helps!

On the lower lip near the corner of my female cats lip, a soar has developed. It is slightly red and dry and swollen . It has the appearance of what a human lip would look like if it was licked to much and a rash formed. It does not seem to bother he
I am sorry to hear that! I do think going to the vet would be a good idea. Cats can get many types of lumps at their mouths. From your description one thing I would want to rule out is eosinophilic plaques. These can be caused by allergies so getting on a low allergen food (I would recommend prescription due to cross-contamination at the manufacturing level) and medications can be vital! Of course it is hard to tell without looking at her so your vet may want to rule tests or take a biopsy first! I hope this helps!

Thanks for using Boop by Petco! This looks like it is due to the tooth causing pressure on the gum causing this ulcer/lesion. I would agree with your veterinarian in that they probably need to sedate or put under anesthesia to be able to better evaluate this region. Then they can treat it accordingly. If it is found to be dental disease, they can correct it then. Best of luck!

Hi. I have a 5 month old kitten. And he has what looks like a cold sore on his lip, he has had this for a few weeks now. Could this be a cold sore or something else?
Hi there and thank you for using Boop by Petco 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!

Hello I have just recognized a problem on my cats lip. Seems as the one in the article I have seen
It is difficult to tell form the picture alone what is going on with your cat's lips unfortunately. It almost looks like she/he has a sore or even infection in her/his whiskers and commissure of the mouth. I would recommend you take your cat to your vet for an exam. She/he may need antibiotics to resolve this and possibly pain medication is she/he is is uncomfortable. I would also be concerned there may be sores in the mouth that need to be addressed if you are seeing them along the outside. It is possible your cat licked something toxic or caustic causing these problems. I would look around your home to see if there is anything she/he could have gotten in to. I hope your cat improves quickly!

My cat has a sore on his upper lip and one under his chin i believe its from him having a plastic water dish what can i do to heal them? I attached two photos of the one on his lip
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!

My cat (2yo) has a sore with what appears to be a scab peeling off on her lower lip. The area appears swollen and painful. What could this be?
Poor Lou. Thank you for the picture of the sore on her lip, it's very helpful. This sore could be from an injury or it could be something known as a feline eosinophilic granuloma complex. The exact cause of feline eosinophilic granuloma complex is unknown, but research studies suggest that a form of allergic response (hypersensitivity reaction) may be involved in the majority of cases. Unfortunately I cannot make a diagnosis from a picture alone, so I do suggest having her seen by a vet for this issue, who can diagnose it and treat it. I would give her vet a call now to make her an appointment. I hope this helps!

Hi, my name is Ashley and i have a cat. I have a feeling there is something wrong with my cats lip. It looks like sore like symptom. And i would like some help trying to figure out what it is.
A picture might help a little more, but sores on the lips of cats are pretty common, and can be caused by many things, including dental disease, rodent ulcer (see article below), autoimmune disease, cancer, etc. To know for sure, your cat needs to be examined by a vet and a sample of the lesion examined under a microscope (either by a needle sample or a biopsy). https://www.petcoach.co/cat/condition/eosinophilic-disease/
