My cat has a brown-red scab with pink edges. Is it an infection?

If it's scabbing over, I'd let it be but if Tink keeps scratching at it, then take her into the vet. Also take her into the vet if it appears infected. Signs of infection include redness, swelling, pus, and the area being warm to the touch. I hope this helps!

It could be that Ruby sustained a wound from trauma that has caused the scab, and I would monitor it for now for signs of infection. These signs include redness, swelling, warmth to the touch, and puss. Should any of those signs be seen, I would take Ruby into the vet for antibiotics. I would not put any topical treatment on it. Although quite safe on superficial wounds, cats groom and ingest most of the topical ointment you apply and therefore should be used only under direct veterinary supervision and if there are no other appropriate options. Many human ointments contain multiple other ingredients which are not necessarily safe to be swallowed. Hopefully, it should heal just fine on it's own.

It looks like it may be a wound that has developed a scab. This may habe been from a cat fight wound. I would be concerned with how deep this wound goes and a secondary infection. You can make up a light brown solution of Betadine and sterile saline to clean the area and monitor it. If it worsens, I would strongly urge you try to get in to see a vet for proper treatment.

Have you put any medicine on that area such as flea prevention before it was noticed? Sometimes that is a sign of a reaction from a topical. Another area to check is his ears, sometimes they can scratch their neck instead and. Cause a wound if there is an infection or mites. If it doesn't improve then your vet can check for an infection or an allergy that could cause it

Poor cat. This looks wide enough where it should at the very least get a topical treatment. You can try an over the counter antibitoic ointment or spray from your local pet store. Ask a store representative as to what is available in your area. You should also clean this area with Betadine diluted 50:50 with warm water to help keep bacteria and infection at bay. If it doesn't seem to be healing well in the next few days, then a vet visit is warranted at that point. I hope that this heals up well soon! Best of luck moving forward. Take care. : )

The lesion in the photo looks to be an infection. It is not possible to determine the severity or how deep it is because if the crusty buildup on the surface. This may be bacterial or fungal, but it should be looked at by your vet and Jibgkes will at least need a prescription antibiotic or anti fungal medication. If the wound under the surface is deep, surgical debridement may be necessary.

It actually looks like Lulu’s wound is healing very nicely. The redness will continue to resolve slowly over the next few days. I would recommend continuing the ointment your vet prescribed until the area is completely cleared and appears pink, instead of red. Another scab may form and this is fine. Just continue to keep the area clean, dry and medicated. It looks as if it will be completely healed in about another week. I hope this helps.
