*1 part by volume cooked wholegrain rice (you can cook large batches & freeze it for convenience)

*2 parts crushed barley or oats, or a mixture (or porridge oats)

*1/2 part millet or cockatiel seed

*1/2 part molasses - packed full of vitamins, and sweet too, so it binds the food together AND the mice like it.

The trouble with the rat race is that even if you win, you're still a rat. 
~Lily Tomlin
The kangaroo rat can cover ground at a rate of 17 feet per second. It can leap as much as 18 inches straight up and can switch directions at the peak of its jump.
