Mice are great pets for people of all ages and are fairly easy to care for. You should start by providing the right housing. An aquarium or wire cage with proper substrate is great for a mouse. You should also feed your mouse the right diet. A combination of commercial food and treats works best for a mouse. You should also make sure your mouse is healthy. Make sure it gets enough exercise and take it to the vet if you notice changes in behavior such as a lack of energy.

  1. An aquarium can be a good choice to keep mice. If you opt for an aquarium, make sure it's at least 10 gallons (about 38 liters) and has a mesh lid to prevent a mouse from escaping. If you have one to three mice, a bigger aquarium is necessary.
    • Four to five mice need at least a 15 gallon (about 58 liters) aquarium. Five to six mice need a 20 gallon (about 78 liters) aquarium.
    • In general, however, bigger is better for any mouse. Get as big of an aquarium as you can fit in your home.
  2. A wire cage is also an option for mice. While an aquarium is usually a better option, you can opt for a cage if you cannot find an aquarium. If you get a cage, make sure to select one that's safe for mice. The size of the cage should be at least 24 by 12 inches (about 61 by 30 centimeters). There should be no more than a quarter inch between wires, as this will prevent mice from escaping.

  3. Substrate is the material lining the bottom of the cage. For mice, opt for shredded paper that does not contain ink. Line this on the bottom of the cage. A few centimeters of substrate is adequate for a mouse. [1]
  4. Mice are sensitive to heat and cold, so it's important to keep them in an area that's consistently room temperature. Do not put your mouse's enclosure next to heaters, furnaces, or other sources of heat. You should also avoid cold, drafty rooms.
  5. Certain types of houses are dangerous for mice. Never keep a mouse in a cardboard box or a wooden enclosure, as mice may chew through these materials. You should also be careful about mice habitats, with a lot of tubes and accessories, sold at pet stores. Mice can get trapped and injured in these kinds of enclosures.
  6. A mouse's enclosure needs daily cleaning. Each day, use a cat litter scoop to remove soiled bedding. Once a week, you should give the enclosure a thorough cleaning. [2]
    • Place your mice in a separate container. Remove all the bedding, any cardboard toys, and food and water bowls.
    • Use dish washer detergent and water to wash the insides of the enclosure, as well as food and water bowls and plastic toys. Allow everything to dry completely.
    • Replace all the bedding with new material. Place food and water bowls, as well as plastic toys, back in the cage. Discard old cardboard toys and replace them with new ones.

Feeding Your Mouse

  1. Pellets and seeds are sold in pet stores specifically for mice. Mice do not require a lot of food. A tablespoon of pellets or seeds per mouse should be enough.
    • Go for a ceramic bowl over a plastic one as these tend to be sturdier and more resistant to chewing.
    • Pick a smaller bowl. You do not want the bowl to take up a lot of space in your mouse's home.
    • Make sure to place the food bowl far away from the bathroom area.
  2. Healthy treats are okay once in a while and can help with your mouse's health. Dog biscuits or treat branches are good for chewing. You can also give your mouse fresh fruits and vegetables from your own kitchen.
    • Feed your mouse things like greens, blueberries, and apples once a day. Opt for small amounts and chop bigger fruits into pieces to help your mice easily swallow them.You can also feed them grains, seeds,hay,etc.
  3. Mice are nocturnal, so it's best to provide food close to nighttime. You should also provide a continual supply of water at all hours of the day.
    • Make sure to set some kind of alarm or alert. Mice need food every day, so you should not skip meals. It's like you skipping a days worth of food.

Keeping Your Mice Healthy

  1. Mice are generally afraid of people, so minimize how often you handle your mouse. When you do pick up your mouse, do so in a safe fashion. Set a treat in your palm then lay your hand flat at the bottom of its cage. When it climbs on, gently lift it up into the air. Hold your mouse close to your lap if it is not comfortable being held. You can then pet and interact with your mouse. If your mouse is squirming and nervous, place it back in its cage.
    • Never grab a mouse by the tip of its tail and do not squeeze a mouse with your fingers.
  2. Mice are active animals that need plenty of exercise to stay healthy. An exercise wheel is vital for any mouse's cage. However, always opt for a plastic one over a wire one. Mice can easily get trapped and injured or even killed in a wire wheel. [3]
    • You should also provide toys. Inexpensive toys, like cardboard rolls from paper towels and toilet paper, are safe for mice to play with. You can also pick up commercial toys from a local pet store.
  3. Mice should be active and alert. They should eat and drink regularly and breathe and walk steadily. If you notice any of the following changes in behavior, see a vet: [4]
    • Lack of appetite
    • Lethargy
    • Discharge from the eyes or nose
    • Diarrhea
    • Weight loss
    • Skin lesions
    • Overgrown teeth
  4. Extreme temperatures can cause health problems and even death in mice. Make sure you keep your mice in an area in your home that's room temperature. If anything causes a sudden change in temperature, such as a heat outage, move your mouse to a location where temperature is stable. [5]
  5. Household pets like cats and dogs may view mice as prey. Pets like ferrets and snakes may also prey on mice. Keep mice in separate rooms from other pets and make sure their cages are secure at all times. [6]

  • Question
    Are mice good pets for little kids?
    Community Answer
    Yes, but if the child is younger than about 8, they should always be supervised when handling the mice, and they should be kept out of reach in case the child decides to hold it without permission. Young children also touch things that they shouldn't, like their noses or mouths, so have them wash their hands after handling the mice. An adult should also make sure that the mice are being properly cared for, in terms of feeding, keeping the cage clean, etc.

    They are lactose intolerant, so no. It would do more harm than good.

      Tips

      • Remember that mice get scared a lot and sometimes they don't like to be picked up a lot or at all. Do not handle your mouse if it doesn't seem to enjoy handling. Give it some space. Pick it up again, when he is more responsive.
      • If you have only one mouse, give it a lot of attention. Make sure you play with it daily.
      • Female mice enjoy life a lot more with lots of attention, and one or two other female mice for company.
