So my '08 bp has just about passed adult mice being big enough for her(the local f/t ones at least), the ones I get are 28-32 grams, and alice weighed in at 340 grams tonight.
I'm sure that adult mice are still good enough for a few more feedings, but I was wondering about switching her to rats.. I'm unfamiliar on rat sizes, but what should I be looking into to be the next size to move up?
