Thanks for the quick replies everyone...

He did have one runny poo when i first got him home, but hes gone twice since then and they both seemed fine... Kinda wierd huh? I just assumed the first was due to stress of a new enclosure and such, but we'll see. The 15 day guarantee also says that if i notice something wrong, they will schedule a free vet visit for him, so i suppose i could do that if need be, but i checked him as best i could for mites and didnt see anything...
