Pet's info: Cat | American Shorthair | Male | neutered | 1 year and 7 months old | 8.4 lbs
My cat was missing for the last 5 weeks. Just reunited and I noticed on his spine a bump. Not sure what happened if maybe he fell? Doesn't hurt him or affect eating. Should I Ice it or do anything? He is 1 year 7 months old and has had no issues before.

If the swelling is warm to the touch and slightly depressible, then this is most likely an abscess (pus filled pocket) which is caused by some kind of trauma or puncture to the skin. This is a very common occurrence in cats that are outside or go outside for a brief period of time. To treat this you will need the help of your veteran veterinarian, who can drain the abscess and flush out all of the bacteria, and then put Dusty on a short course of oral antibiotics. Ask your veterinarian about an injectable antibiotic called Convenia, which they can give right there at the hospital. This antibiotic is favored by cat owners because it requires no medication giving at home and lasts for 2 weeks with just a 1-time injection by your vet.
