My cat's drained abscess is swollen again. What should I do?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | neutered | 2 years and 6 months old

Hi, my cat had a bad absess drained at vets 48 hours ago.. He wouldn't leave it alone and made it bleed by scratching it so we had to rush to a pet shop to get a cone so he can't scratch it. The staff helped us as it was so swollen it was bleeding everywhere. Do i need to clean it an drain it again as it's slightly swollen up again as we was only told to gently clean it with salt water. He had 3 incisions where they drained the abscess which have stopped bleeding.

The main thing here is that the pus was drained from the abscess at your veterinarians clinic. Once the infected material is flushed out, there can still be fluid accumulating at the site of the abscess. You can apply a warm water washcloth to the area to keep it clean. I would just dab the area and not "scrub" to keep it clean. If it becomes as swollen as it was prior to your veterinarian's treatment, I would take him back in and have it looked at. I am hoping he was placed on antibiotics and an anti-inflammatory as both these will help in the healing period. Keep the cone on until this heals fully as well. Please feel free to contact me with any questions / concerns you may have.
