I bought a trio of afs rats at a reptile show back in February. I added a female from a local shop in hopes I could freshen up the blood line in the next generation. I feed them a base diet of dog food kibble that is 21 percent protein and add a little kitten kibble 40 percent protein, and some hamster food that has some seeds and grain. I give them apple or strawberry or whatever fruit I have and some fresh clover from the yard daily. They all seemed to grow ok except for the female from the local source which is about half the size of the others. I keep them in a 20 gallon tank with a wheel and a hide. The first female to give birth had only three pups and ate one per day until they were all gone. About a week later the biggest female had 13 pups and after 24 hours began eating them. I took the ten pinkies that were left and put them in some mice nests in some other tubs I have for the mice to foster. At this point I have had these for two and a half months and have not raised a feeder out of them yet. Thoughts or suggestions would be greatly appreciated.
