I buy bedding(when I don't use newspaper) from walmart, or tractor supply. I got some of my racks from Neil Golli at GolliReptiles.com and others from Boaphile(don't reccomend them unless you have plenty of time to wait) and also from the snakeshak people(mind is blank.. who is that?). Incubator from the same folks.. geez... I can't think of the name.. Nature's Spirit? I think that's it.
Rats from my local supplier and from Rodentpro.com
I think that' about all I ever buy.
