How long can pet mice live without food and water?

They can live healthy and fine for up to a week. After that, it can still live but will be very skinny that it will have to go in a special diet to regain the weight lost. Dont worry, I'm sure you'll find it in 2 days at the most. Whenever I lose my hamsters, it takes about a day to find them. Just make the house silent and listen for scratching. It will be the mice. My hamsters usually run off under the fridge where it's warm and dark. Then, I sit and wait for them to come out and put a carrot in the floor for them to smell. If there's holes in your floor or on the sides, they could've gone inside the wall. My hamster did that once, he kept scratching until he came out by himself at night. Be patient and check in all the rooms, close the doors too so they won't run off any further. Check under sofas, cabinets, beds, and in closets. Also, watch your step so you won't step one one of them! If you still can't find them, you can try putting flour on the floor so you can search out the footprints and see where they're hiding.

Well they can live without food the longest water is very important just like it is to humans. So I suggestput out a water cup and they willcome
