Are hamsters as nutritionally good as mice, rats, or rabbits?

Hamsters would have about the same nutritional value as any other rodent. They do have quite a bit more fur which is hard for reptiles to digest. But, if you are just feeding the pinkies then it should be ok. The only down side to breeding hamsters is that they are seasonal breeders. Usually only breeding between april and october. They also have smaller litters. Syrians however will have larger litters somewhere around 7 up to 13. They become ually mature a lot sooner than other breeds as well. Around 4-6 weeks. I would suggest breeding mice. Unless you have something against keeping them.
