How to tell if mice are happy?
I have 4 girls, they are quite skittish about being held, but we've noticed if we gently pet their heads with a finger they stop trying to run and kind of half-close their eyes, sometimes tip their heads back a bit.
I've only ever kept rattos before, and i know if i did something they liked because they'd brux and boggle like crazy. But i don't know if my girlypops are happy or just scared.
They have deep substrate, i hide treats like mealworms in it when i change the substrate so they can dig and find them, and i make their home as cluttered as possible, creating tunnels and hides and stuff out of things like loo roll tubes and cereal boxes. So i am pretty sure they're happy at home, i just want to make sure they aren't absolutely hating being handled.
