My cat has a swollen, leaking bump under its jaw. Is it infected?

Even though a picture would help to understand better the underlying cause, this presentation could be due to a trauma (bite wound) and/or localized spot of skin infection (likely to be caused by bacteria). A check up, appropriate disinfection and possibly antibiotics (oral, topical or in a shampoo formulation) are needed to solve the problem. Disinfection may be started at home with very diluted hibiscrub or betadine or salted water baths. Buster collar may be useful as well to avoid any licking/scratching.

In this case a picture would be really helpful to understand the extension of the damage and offer you the best treatment options. Antibiotics are likely to be needed, but disinfection may be started at home with very diluted hibiscrub or betadine or salted water baths.

A sudden swelling under the jaw could be an abscess. Typically these need to be seen by a vet; as they often need to be lanced/drained to get the pus and infection out; then started on antibiotics. Pain medication may be given as well. If he isn't eating, if he's acting lethargic or otherwise not feeling well (vomiting, diarrhea, any change in breathing) seek emergency care. If your vet's office is closed, they likely have a message with who to call or where to seek after hours care in the case of an emergency. If he's still eating and acting ok, you can call and make an appointment at the first possible time. I hope that helps you! Thanks for asking Petco Pet Education Center, formerly Petcoach!

The area on Leah definitely looks pretty angry and infected. Here's what I would recommend doing. You can either go to the vet and let them take care of this for you, or you can try the following first on your own if he'll let you: -Clip the hair on and around the affected lesion -Scrub the lesion with dilute betadine or chlorhexidine solution repeatedly to disinfect the region. Do not use peroxide as it will delay the healing process -Obtain topical ointments such as triple antibiotic and something with a steroid to help address the itchiness and inflammation -Obtain an e-collar (Cone) to help prevent any additional self-inflicted trauma that Shadow will try to cause -If matters do not seem to be heading in the right direction within the next couple days, seek veterinary attention. If at any time things are worsening, do not hesitate to go sooner. Hope this helps. And while I can't be sure, I don't think you need to fear that Shadow is going to die! It looks like a simple skin infection. Hope this puts you a little bit at ease!
