Monkey Biscuits?

Have any of you rat breeders used these? My wife brought some home from the zoo today and my rats went nuts on them.

The place I got my rats from said he uses those and lab blocks.

I'm going to have to check those out.

I use them...

24/7 I offer lab blocks and monkey biscuits.

Once a night (right before bed) I wet One biscuit for each rat (More for Prego/Mommy Rats)

They love them!

We use mazuri 6F for all our rodents but always give them monkey biscuits when we can. We house them in rack systems and the food is on top like normal but the biscuits we put in the cages with the animals and they go nuts over them. :)
