.... I decided to get two mice for the bp today. He ignored the first one for awhile. I've only fed him a few times, so I'm still feeling out his habits. I turned out the lights to see if that would help, and it kicked him right into gear. Almost immediately, he coiled up into striking position, and nailed the mouse as soon as it got close.
After he swallowed it completely and moved around a bit, I dropped in the second one, and it barely touched down before he was on it. He downed the second one with no problem, cruised by the water bowls, and retreated to his hide.
Anyway, I'm glad for the advice about feeding multiple items, and feel bad for not allowing him to get full prior to now. Should I stick with a couple mice, since he takes them quite well, or try something a little larger? I measured him last night, and his widest point is about 1.75", so it seems a small rat wouldn't be too large.
