Many of the veterinary drugs for dogs and cats are the same as drugs for humans. The human drug equivalents can be ordered from IOPs. I got tired of paying $40+ to bring a previous cat to the vet every time he got in a fight and developed an abscess. If you get the pediatric suspension of amxocillin from a place like Masters, one 7500-mg bottle of the powder is ten courses of antibiotics for about $7 plus shipping. Save one of the plastic bottles with the graduated dropper that the vet sells and weigh out and divide the pediatric powder and store it in little zip-locs in the freezer. It's the exact same stuff. Give the same doses that the vet was using. Do a Google on how to lance a boil. The hardest part is often shaving the hair of a cat or dog near the boil if you want to drain it. You can get a spray bottle of lidocaine local anesthetic OTC that will make it easier on both of you.
