My best trash can is my Dumerils.
There's nothing she won't eat.
One of my live mice dropped dead and I hated to waste it and even though it's far too small prey for her, she just sort of happily sucked it in.
She always gets the small rats that the others don't feel like eating, too.
If the BPs haven't eaten them within a few hours, I toss them to her.
On feeding night, even though she's had her own mega-rat, she'll wait with her face against her sliding window for hours, hoping somebody is feeling too picky to eat.
