There are many factors that go into choosing the right pet. Potential owners have to keep environment, lifestyle, and budget in mind, among other things. While many people choose a dog or cat, these animals aren’t always the best option for folks. Some people do not have the time for daily dog walks or cleaning litter boxes.

For some, mice make the ideal pet. They generally tend to be less time consuming, require less food, and have shorter lifespans. Plus, they are considerably more affordable.

If you want cheap pet mice, you’ll still need to keep things in mind. Mice require a particular diet, must live in pairs or large groups, and can run into health issues. They also require special habitats that are well-ventilated and bedding that needs regular changing.

Before purchasing your mice, make sure you know which species are native to your area. In the off chance that they escape, native species will cause less harm to the ecosystem. Here are eight mice that are cheap and affordable to keep as pets.
