I've decided to get a trio of weaned rat pups to raise them as pets and breeders so I don't have to spend too much money each week to purchase rats for my snakes.

I've been told they are very friendly and not as smelly as mice can get. I have a 20 gallon long I can put them in, or a 10 gallon if the 20 gallon is too large for the trio of rat pups.

I was wondering what type of dog food is best to feed the rats, since I've read some dog foods aren't very good for them to chow on. If you breed/have rats, what do you feed them or what brands of dog food do you feed them?
