I am hiding it in my room because I'm afraid my mom may throw it out too. I have it in an old aquarium beside my bed. It has a top with a screen. I used to have gerbils, but they disappeared. If this is a pet mouse, you can feed it nuts, seeds, vegetables, whole wheat bread crumbs and gerbil or hambster food.
Mice are easy to care for.
They need water and some litter or paper to hide in. It was hard to do all that math with tiny furry paws. I would love to know more about you. Tell me where you are from, something about the humans you have encountered and anything you would like to share. Thank you for dropping by.
