Not producing!

3 to 5 days is likely the problem. A female rat cycles about every 4 to 5 days so you really aren't giving them much opportunity there. Try a nice male in with her and another female, in a larger enclosure, for at least 2 weeks (or just pull the females as they show the typical pear shape that indicates they are preggers).

Just wondering if the mazuri rodent block types matter. If it doesnt then Ill continue.

Thanks again to everyone that helped. You guys rock.
:rockon:

Ill keep everyone updated.

I use the 6f I think it is. All mine are doing great on it combined with the rodent diet listed in the sticky and occasional leftovers.

Mazuri 6F FTW!!

Just to echo...definitely leave them together longer.
