How to treat a rat's ear cut with pus? Does it need a vet?

Updated On September 23rd, 2025

Pet's info: Small Animal | Rat | Male | unneutered | 1 year old

My rat has a small cut on the bottom of his left ear. There was a scab on it for the last few days, but it fell off today. There is, what appears to me to be, a small amount of puss in the wound where the scab was. The substance I see is not oozing or flowing from the wound. What is the best way to treat this and does it warrant a visit to the vet?

Hello. I do not think this requires a veterinary visit. Clean this once or twice a day with a skin antiseptic like Hibiclens ( available in all pharmacies ) & dab the wound with just a tiny bit of triple antibiotic. If this does not heal in 10-14 days, do see your vet. Rats are prone to developing tumors, so you should have a non-healing wound looked at. But if it appears to be healing with this treatment, it is very unlikely to be worrisome. Thanks for using Petco Pet Education Center, formerly Petcoach.
