Please Help! Infection? Mites?

[virgooftheearth]

My Rudy has a bad I fection I saw him limping the other day and when I checked closer his feet were swollen. I took him into the house and immediately soaked him, cleaned his feet and legs, and what I thought was mites and has been treated for them, (poultry spray), seems to be an I fection of some kind, any ideas? Am I going to have to put him down? I called the MSPCA and they will just put him down, I think I need antibiotics.

Swollen feet can sometimes be gout. What are you feeding him? I see no raised scales so I don't think it's mites.
