Welcome to YT!!
You just jumped right in with both feet,huh? Most of us warn how addicting they are and they are like potato chips - you can't have just 1. Well, you took care of that right off the bat.
I had/have my hands full with one - potty training and the like. Kudos to you!!
Please post pics of your littles ok? We love us some pics around here.
Oh, and very happy to hear you aren't planning on breeding them. Make sure you get them all spayed and neutered in time, then, ok? Two males and two females - all intact - will lead to complete chaos lol. Just sayin
