I am thinking about starting a small colony of 1.3 or 1.4 to provide food for my snakes because one of my new additions won't take f/t. I am concerned about the smell as this colony would be raised in my home. With a small number of rats, and changing the bedding once a week what kind of odor should I expect?

I would also appreciate if anyone can provide information regarding bulk food, or bedding and the best places to buy these, pet stores in my area are somewhat expensive and have small bags of food(they carry 2.5 and 5 lb bags and I would prefer 25-30 lb.)

Thanks so much for any help, the idea of breeding feeders is new to me.
