An allergy to rats is problematic. You could try seeing if you have an allergy to African Soft Fur (ASF) Rats. I used them for a while-people say they have 'tame' colonies that don't bite--I had neurotic cannibals with a thirst for blood.
I'm not fond of RodentPro based on past experience--their poor quality are actually the reason I started breeding my own rodents. I'm told that Perfect Prey or Big Cheese Rodents are superior if they have the correct food sizes in stock.![]()
