Food Based on Weight

Is there a chart that any of you support that relates weight ranges to food size for both rats and mice? I've seen the images that compares the different sizes between rats and mice, but I still don't know how to use these sizes to determine what my BP should be eating. Last Friday I recorded 522g and he hasn't pooped since I got him, but I've found a few urates.

If he's 522 grams then he can be on small rats.

Does his back end look full, like he has "sausage butt"? If so he's going to give you a present soon.

I have used this for all my snake needs when in doubt DISCLAIMER: only if it matches the widest part of the body or is slightly larger.http://images.tapatalk-cdn.com/15/08...2f11282a87.jpg
