My cat's leg abscess burst. What aftercare is needed and vet visit?

Hello and welcome to Petco Pet Education Center, formerly Petcoach. That does appear to be a burst abscess. Without examining her it's impossible to know for sure, however it resembles and has acted like an abscess. Ideally she would be seen by a vet, they would flush it out with warm (not hot) salt water (1 teaspoon in 1 cup of water- your vet would use sterile saline) and then likely get antibiotics and pain meds. An E-collar also prevents Littlecloud from licking and introducing more bacteria into the wound. If you cannot go to a vet, I recommend flushing it/cleaning it with salt water. Do not use any topical creams, just leave it open to drain. Clean it twice a day with the salt water, and try to prevent Littlecloud from licking at it or chewing at it. The main pain has now gone since the abscess has burst (the pressure is relieved) . Do not give any human pain medications as these are often very toxic to cats. Best of luck with Littlecloud!

Thanks for using Petco Pet Education Center, formerly Petcoach! This is indeed most likely due to the abscess. I would be suspicious that some of that pus and inflammation has migrated to the leg and is causing pain as well. At this point I think this may be require more investigation into the underlying cause of the abscess. I would be suspicious of foreign material that has migrated and is underneath the skin. If that is the case, surgery and possibly further diagnostics like a CT scan as well as long courses of antibiotics may be needed to treat this appropriately. A culture of this wound should be obtained if that has not been done to make sure that the correct antibiotic is used. I recommend that you have Spock reevaluated by your veterinarian for further assessment and treatment. Good luck and have a good night!

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. Buster collar may be useful as well to avoid any licking/scratching (if any).

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.

If your cat lets you do it, you can bathe her paw in a warm epsom salt solution twice a day. This should help ripen the abscess. Since I have not seen the abscess, I cannot tell you , how long it should take until it bursts, but I think by the latest on Monday, it should have opened.

It looks like it may be healing. If it isn't big, full of pus, painful to him, he's eating, and isn't lethargic, you can wait until Monday to have him seen. Otherwise, take him into a vet immediately.

A check up, appropriate disinfection and eventually antibiotics (oral, topical or in a shampoo formulation) are needed to solve the problem. Disinfection can eventually be started at home with very diluted hibiscrub or betadine or salted water baths. Buster collar may be useful as well to avoid licking.
