I have an 800 gram female right now that I've been feeding small rats around 60-70 grams usually. When I was picking up a live rat today the guy gave me a larger small that weighed about 98 grams. Just fed her, and she took the rat down fine, and fairly quick. I'm wondering should I feed her rats around that size from now on, or still stick to the 70 gram rats? When I was checking out the size chart on rodentpro, it said a 98 gram rat was a medium.
