Liquid injectable penicillin can be bought without prescription at a feed or farm store. The dosage for cats is 1/2 ml (.5ml) per cat (you need not worry about per-pound.) Small syringes 1ml, 3ml are easiest to use, get 20 or 24 gauge needles to use on the cat, and if possible, one larger gauge needle (16-18) to withdraw the liquid from the bottle.
