Okay so I've killed the mice most humane possible way to me which is doing a cervical dislocation which really was uncomfortable that my hand was actually shaking. But I respectfully said thank you to each time I do it.. just my way of respect.

But now my bp seems like it's scared to eat , maybe the mice might be abit too big to what it's comfortable too, so another question here is

1. How do I switch smaller mice to a little bigger (pinkie to fuzzy)
