So I had a rather lice problem and treated them with some Ivermectin. The last dose was on May, 12. My friend just got an enchi and is eating rat fuzzies. I have 30 babies at the moment all a little over a week old. I wanted to give him a few, but how long should I wait? Do I have to wait months? Weeks? I really don't know. My pet shop currently only has small mice, he is eating two a sitting that's 12 bucks a feeding. Just trying to help him out a bit. Thanks!
