I have several rats since I breed. Don't worry, I am a responsible breeder and most of my babies are sold before being born, and a lot of my rats are sterilized before they leave as well.
I really adore my pets! I run an exotic animal rescue and most of my pets are rescues. Lucy came from the Joshua Tree Tortoise Rescue in California, many of my rats are rescues, my soon to be possums are rescues from a non USDA breeder who actually ships USPS..grr...most of the possums are missing tails, have gashes or missing eyes ect, my girl hedgie Flower was a rescue and was infested with mites when I got her, as well as covered in feces, my gecko was a rescue ( I had found him stuck to a glue pad made to catch rats and had to unstick him ), my mouse was a rescue my cat brought to me, Ewok is my kitten whom I bottlefed since he was two weeks of age (he was brought into my vet clinic), and I guess you can call the roachies rescues too because they were going tobe fed to animals...yikes!
I have several different types of rats like hairless, tailless, odd eyes (two different colored eyes), and several different colors....we even have merle rats! We also have curly coated types as well. All my rats are pedigreed and bred for health, temperament and type, and yes we have rat shows as well.
