One thing I noticed about Doggy Bag is I waste much less. The Pedigree fell through the hardware cloth a lot and got peed on, so it got wasted a lot. Doggy Bag doesn't.
And it seems to fill them up more. They're eating less of it, but still eating (meaning it's not just them not eating the food).

I think my colony will be better now.

Rats are hard to get on Craigslist around here. People either flag the ads, or it's one of those "NO SNAKE OWNERS" ads...and I am a bad liar. Haha.
