rat rack

[BellyDragger]

Linds is right we use plastic Coke bottles for our rats so we don't have to fill them as often (our ratios are 1.5). In the winter they seem to last the week but in the summer we could change our bottles sometimes up to 3 times a week. It all depends on alot of different factors in the above posts.
Our mice we usually have to fill waters twice a week (1.4 ratios).

Cheers
