For those who use an undertank heat mat, particularly ones made for people that don't automatically shut off on their own, what do you suppose (or know) the cost in electricity is to heat an 18-20gal bin? I know in Summer it'll be perhaps cheaper, depending, but I'm wondering if anyone knows or has a guess. I'm trying to justify keeping them if I move, as they're new. Keeping the roaches, which can bring in some money, I think it'd be a short *hop* to keeping Banjo (my toad). This is not a cat forum so I won't even go into that.
Unique situation as mortgage company (I'm a renter here) took over utilities a while ago without warning, so I can't just look at my electric bill and see. They're just regular sunbeam heat mats, tho one might be a conair (cheaper to buy with less controls, but effective). With ACs running in the house, it will be impossible to tell what my roach keeping is costing. Just looking for some input, if anyone has any.
