I haven't had much luck with breeding mice yet. I just picked up a completely new batch and started from scratch today. Got one male and 2 females from petco that were in seperate cages. Just cleaned out and set up the cage again.

I had the previous set of mice for over a month and I didn't even see any signs of pregnant mice, so they became snake dinner.

Here is a pic of the cage, is there anything wrong with this setup? Does anyone have pics of what their mice breeding setup looks like?

I also weighed them this time, is this a reliable way to determine if they are pregnant? The male is 23g, female #1 is 23g and female #2 is 26g.

Thanks
