Very briefly, I have tried the following rodent foods with rats, mice and ASF's. I list them in the order I like them, based on a conbination of results and cost.

1. Mazuri 6F
2. Native Earth 4018
3. Mazuri Rodent
4. Doggy Bag for short periods (not suitable for mice/ASFs)

Unacceptable - Kent 19%

YMMV
