I have a 2-year old male who started refusing to eat at the end of March. I'm not doing anything differently, and he gets excited when he smells the food, but then never strikes.

I was thinking maybe if I went out and bought some different rats, or even some mice, he'd find them more appealing? Is that a good idea? Does anyone know a good place in Chicago to buy frozen feeders (he's only ever had f/t)?

Any other thoughts on tempting a picky eater would also be appreciated.
