Yeah, they do that sometime, but I take the hint and get them food as soon as I can. I think the main problem is that i waited WAYYYYYYYY too much time to switch them to rats. They are very picky eaters and used to refuse rats all the time, so I just kept them on largish mice. They're finally eating rats now and I think they're already putting on weight--and They're stopped cruising since I started them on rats too... I think that sounds pretty accurate, don't you?
And, just wondering, what is the purpose of the fectal? Could parasites be causing a increased motabalism or something? And do they need special equipment to do it?--or does a petstore have the knowhow?
