luvmychicknkids is right, its very easy to breed rats,lol.
But I only breed certain rats, I breed to better the fancy rat,not just to have babies. I'm very picky about which rats I breed.
Rats will give birth to an average size litter of 6-24 babies. (Most common averages are 6-15 babies.)(Large litters are more uncommon than smaller ones.)
They are so cute! Lots of people thinks pinks are ugly, but I think they are so adorable. I raised PEW mice, so I get no color variety. I would love to get a couple rats, but of the same sex. I dont need rat babies,lol. I've had them before, but we havent had any in a long time.
