Snickers weighs about 580 grams and the rat weights about 50 grams.
I'm going to give her that rat tomorrow night and am going to stop buying mice from now on.
Now I'm not sure if I should buy a slightly bigger rat in the future or not and if I continue buying her the same sized rats as she will be eating tomorrow I'm not sure how often to feed them to her.(not sure if I should do it every 2 or every 3 weeks?)
My bp is at 675g and he is on the last of my 60g rats every 5-7 days. I'm kicking it up to 100g rats (closer to 15% of his weight) and on to a 7 day schedule.
He has been on 50-60g rats since he was 350g so don't worry, that rat is not too big.
