Took a sample to the vet for a fecal - first time to a vet. The snake is 345gr and approx 4 feet long. The snake seems healthy enough - active, eats, drinks, poops, sheds fine. They said it had worms (hook or pin) I can't remember. They gave me 2, 50ml doses of 10% Ivermectin to give orally two weeks apart. Also have another cornsnake and a milksnake. All snakes are in aspen bedding. They are housed separate but are fed in the same feed box. All snakes are fed f/t mice of appropriate size. Most of the time the mice are from an online seller but occasionally I get some f/t rat pups or mice from the pet store.
Does this dosage sound right?
Ivermectin can be fatal if misapplied? Are there any other options?
I assume substrate needs to be changed and everything sanitized to prevent reinfection?
Will the other snakes most likely need treatment?
