Low odor rats and mice for new colonies

[Freakie_frog]

Twice a week? My supplier of feeders told me daily cleanings were mandatory...

This definitely makes me feel better.

I breed a couple of hundred rats. In 16x21x7 tubs and I only clean once a week. Everyday is totally out of the question. Now I do clean every 5 days during the summer. The higher temps means they drink more which means they pee more and it turn more smell.
