i was highly considering that also. im thinking next time ill get a rat for my large male BP franny and a small rat that is a little larger than an adult mouse for my small male BP skippy. skippy has great feeding response but will not take down a second mouse like franny does. thats why i want to start skippy on rats that way i can get his weight up to what i think it should be as he is about 10 months now and i think he is small for his age.
