What type of mouse food?
Give them lab blocks – preferably not made by Kaytee. I’ve heard from quite a few sources that Kaytee food, even their blocks, aren’t the best for animals. Teklan and Mazuri are better lab block brands. Seed mixes don’t contain all the essential nutrients, especially if tyour mice only eat the ingredients they like. They also contain a lot of filler like corn, which isn’t good for them. Mice can be given fresh vegetables and fruits several times a week. Some good treats are bananas and grapes (healthy, too). Peas and fresh corn are a good idea too. My rats also like apple, pear and types of melon.
