Why is my cat's face swollen and red below its jaw? Is it serious?

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!

Although a picture of it would help to determine the underlying cause more specifically, this presentation seems to be likely related to a tooth abscess/infection. A clinical examination at your local veterinarian is essential to confirm these clinical suspicions and treat appropriately. Antibiotics may be needed.

Hello and thank you for contacting Petco Pet Education Center, formerly Petcoach. Facial swelling in cats is usually related to abscesses, either from external wound (scratch, cat fight) or from dental diseases. Please, take Bro to your local vets to confirm the diagnosis and to start treatment for him.

She is a cutie! This could be from an insect/spider bite that has cause a local infection/abscess which is why is has started to swell. This could potentially be a cancerous mass that has caused an inflammatory reaction as well. Since it has recently become swollen, I would strongly recommend for your vet to take a look at it. Your vet will be able to aspirate the mass or swelling if needed. They can even take X-rays if needed if they are concerned about sinus or honey involvement. They will also be able to start her on some antibiotics and an anti-inflammatory if needed. I hope this helps!

Facial swelling can be caused by an allergic reaction to something such as an insect sting or spider bite, an abscess from an injury, or even an abscessed tooth (unlikely in such a young cat). I would encourage you to have him evaluated by your veterinarian as soon as possible. Depending on what the diagnosis is will determine what medications are recommended. Best of luck and I hope he improves soon. Thank you for using Pet Coach.

Thanks for using Petco Pet Education Center, formerly Petcoach. I'm sorry to hear Arpy is having facial swelling. Swelling like you are describing can be due to a variety of reasons, including infection (such as an abscess), a problem with a tooth, a growth, or an allergic reaction, among others. I would recommend having him evaluated by a veterinarian, as medications (such as an antibiotic or an anti-inflammatory) or even a dental procedure may be necessary to help resolve it. Good luck!

I would recommend having your vet examine Mochi to see what is going on. It looks like there is a little hair loss as well. If your other cat scratched her and some of the bacteria from the claw punctured the skin, you may not see any blood, but she may have an abscess under the skin that needs to be treated. An abscess can be red and painful, so that may be why she does not want it touched or inspected. Good luck! I hope that was helpful. Thanks for using Petco Pet Education Center, formerly Petcoach.
