Can my indoor cat get a parasite hole under its arm after a fight?

That looks like a bad bite and needs to be seen by a vet right away. Cats that go outside are more likely to get into fights with other cats, and these wounds can easily become infected. Your vet can clean and drain the wound, and provide antibiotics, pain meds and other treatments as needed.

If Felix got out, he may have gotten into a fight with another cat, gotten bitten, and it turned into an abscess. It sounds like the abscess has burst, but if it's painful, he does need to see a vet. I would take him into one first thing in the morning.

These could indeed be fight and bite wounds. Usually they heal by themselves, however sometimes they turn into abscesses which would need to be addressed. Check for swelling, pain , fluctuation, fever, pussy discharge. If any of this occurs, take Sivko to a veterinarian for an exam.

I am so sorry for your cats injuries. Please take her to your vet to have these injuries cared for properly. These are too extensive for at home treatment. Until you can get her in to your vet for much needed wound management and antibiotics; it is best to clean this with Betadine diluted 50:50 with warm water to help antiseptically clean the area. You can also try shaving the hair around the wounds to help remove dirt from the area, but only do so if your pet tolerates it. If not, then its best to just let your vet do it, as this is a crucial step in allowing these areas to heal well. I do hope that you are able to seek medical care for Kiara soon! Best of luck and take care. : )

It sounds like Kitty most likely has an infection in his skin. Abscesses are very common in outdoor cats. I would recommend to make an appointment at the veterinarian's office to have him checked out and the abscesses treated. They may also want to test him for feline leukemia. I hope Kitty starts feeling better soon!

That does look suspicious for a bite though it could also be a scab for many reasons. I recommend to have him examined by the veterinarian if there is a chance he got in a fight. Bites often turn into abscesses and giving him an antibiotic as soon as you see the wounds can help prevent that. I hope this helps.

It could possible be a wound from a cat fight, but other possible causes for a spot that looks like this include an eosinophilic granuloma, tumor, abscess, among a few other things. If it doesn't go back to normal in a couple days, or if Felix isn't eating like normal, he should get checked out by a vet.
