Our rats are kept in proper rat cages as our pets, not in lab breeder cages or really useful boxes. Fed on premium rat muesli and vegetables and are played with daily. We have lines of chocolate siamese including dumbos that are producing the odd recessive double Rex. We also have some red eyed devils, dumbos, straight furred and Rex. We produce the odd solid rare blacks and blue with no white at all, we also see some rare chocolates as well. Our rat breeding has even rubbed of on our daughter and grand daughter who keep rats and occasionally breed too!
