What should I look for in the best mouse food?
Choose a complete diet made for mice with about 16 to 18 percent protein for adults, around 4 to 6 percent fat, and lots of fiber, usually 10 percent or more. If you get pellets that are all the same or a block, that helps prevent selective feeding. Options with vitamin and mineral fortification help your mouse get balanced nutrition through their life. Pick a bag size that will be finished within a couple months to keep it fresh and make sure your mouse will accept it.
How can I tell if a mouse food has gone bad?
Throw out food that smells stale or spoiled, feels oily or wet, is clumping or discolored, or has any mold, bugs, or webs. Pellets that have become very dusty or crumbly and mixes with seeds and nuts that smell bitter or like old paint are likely oxidized and unsafe. Always check the date on the package, and if your mouse suddenly stops eating their usual food, look closely at the rest and replace it if you see any of these signs.
