My cat was attacked by another cat and now has a swollen chest. What's wrong?

Poor guy. There are a lot of wildlife critters and probably a fair number of strays out and about, depending on your neighborhood. The swollen not to the touch area is likely an abscess (infected pocket caused by a puncture wound). You will need to see a vet to have this abscess drained and then have him placed on a short course of antibiotics to help this heal properly. I would consider keeping him indoors more often and fixed if he isn’t already, because intact males typically get into more fights and sustain more injuries. Best of luck with your cat. Take care.

Thanks for using Petco Pet Education Center, formerly Petcoach! You could try to keep it clean but aside from that, I am afraid that he will need veterinary care. Puncture or bite wounds can get infected rather quickly and result in a fever which may be why he is not eating. They can form abscesses that require local treatment and antibiotics. You could perhaps consider taking him to an emergency veterinarian who is open over the weekend. Good luck and have a great day!

Thank you for submitting your question regarding your cat. She will need to see her veterinarian to have the swelling evaluated. It is likely another abscess. She will need to have it lanced to allow the infection to drain out. She will need oral antibiotics as well. I hope this information helps!

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.

I am sorry to hear about Clover. It definitely sounds like he needs to go to the veterinarian for this issue, especially since the swelling is worsening. We would worry about things like abscesses due to a wound, infected/abscessed tooth roots, and more. The vet will examine Clover and depending on their findings may recommend additional testing or treatment.

It's possible Chse may have an abscess if the area is swelling and painful on touch. Abscesses, or infections under the skin can happen if she recently got into a fight or had another wound occur. Other possible causes can include growths, skin infections, potential muscular hernias, allergies or even parasite bites. Having it checked out by your vet is best to find the underlying cause and start on treatment. Until you can get to the vet, keeping her from licking or chewing at it with the use of an Elizabethan (cone) collar is best to prevent further irritation.

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!
