As with any pet, there are foods that you can feed them and foods you can’t feed them. For instance, you shouldn’t feed your mouse junk foods consisting of sugar and salt like chocolate, chips, etc. Mice are not used to eating sugary or processed foods and often find it very hard to digest. If your mouse gets into your snack pile try to judge how much was eaten and call and report it to your vet. Your mouse may need to see your vet. If your vet doesn’t need to see your mouse, you may need to monitor your mouse for any signs of stomach upset, constipation, etc. As for foods your mouse can eat, you should put together a diet pellet mice food. Look for food that is marked safe for mouse consumption. Ask your vets Aurora, CO about feeding small pieces of produce such as turnip greens, blueberries, celery, bananas, broccoli, apples, and peas are also safe.
