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.
