My cat's chin and lip look infected. Should I take him to the vet?

This looks like a mild skin infection. I suggest you use these medicated wipes on the affected area once a day. If no improvement in 7-10 days then Pepper should be examined by your vet. ( https://www.allivet.com/p-5393-douxo-chlorhexidine-3-ps-pads-for-dogs-and-cats-30.aspx )

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.

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!

This looks like a small, localized spot of infection, sometimes referred to as a hot spot. If the infection is contained to this one area you can try to treat it at home with some topical antibiotic ointment (like Neosporin). If this does not take care of the problem, or if there are other areas like this on her skin, I would recommend having her checked out by your vet so a systemic antibiotic can be given.

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!

That does look pretty serious and irritated. I would bring the cat to a vet ASAP for an exam and care to determine the exact cause of the problem. Walmart is unlikely to have the right medication and without a diagnosis from a vet you won't know what to get anyway.

Hi and thanks for your question this morning. From the picture, it looks like a puncture wound or bite wound that has become infected although it could be other skin issues like a fungal infection, parasitic infection, or a bad bacterial infection. Keep the area clean with a mild cleansing cloth a few times daily or 3% hydrogen peroxide on the wound until you can take Snowie into your veterinarian- snowie may need to have fungal or bacterial culture done on the wound and may need to be on antibiotics or another medication for a while. I hope she has a speedy recovery!
