Word to the wise: Rodent Pro is your best option for some sizes of rats right now (mainly larger rats). If you need anything above smalls, may want to focus on Rodent Pro. Had to order Medium Rats and Small-medium rabbits tonight, and the cheapest price I could manage was through Rodent Pro for the size (Layne Labs was quite a bit more$$$ and my normal new supplier Loxahatchee rodents were out of mediums). Oh well. . . at least I only ordered 100 mediums and a half dozen rabits. That'll last me the next 2 months.
