About twice a month I find a really bloated rat, I have only seen the pups to weaned bloated, and then it seems I find them dead. I fed them Mazuri 6F, then I switched to the Native Earth until they quit selling with the free shipping on auto-ship, and now I will be going back to Mazuri 6F. I have always once a week given them spinach leaves and sometimes I give carrots.
Is the bloating something normal on occasion?

I just separated a newer female into the maternity rack because she looked pregnant. After about a week I put her back with the male because obviously she isn't pregnant. But she was that "round" to make me think she was pregnant.

Not trying to be gross but can rats relieve gas in their stomach through flatulation or burping?

Anyway, just curious if anyone else has seen it.
