Our albino spider female had been a super picky/finicky eater for the last year and a half. Only ate mice and you'd be lucky to get more then one in her a week. That was until I moved her into her new and larger enclosure. Now she is the most aggressive eater of the bunch. Any movement in the room and she is poking her head out of her hide looking for the next meal. Went from mice to med rats just like that.
