He was eating live, which is all I have ever tried to feed him. The bedding is care fresh. I only try to feed him once a week so as not to stress him out. I have looked for one of those thermometers and can't find one, what department should I look in? Do you have a picture of one so I know what to look for? I check him over very closely every time hold him and he is clean as a whistle. Curious, active, tongue flicking and clear eyes. I was thinking of trying a bit smaller mouse too as I read that they won't eat if they think it is too big? I have been trying medium hoppers, maybe I should try small hoppers or large fuzzies?
