Mice tend to spend most of their time nesting or playing. Most active at night they will make full use of everything in their enclosure by climbing, chewing and digging to their heart's content! They require a variety of toys, a wheel and chews to play with so they don't become bored and begin destroying their cage. While they are social creatures and thrive in groups, males should be kept in larger enclosures to ensure there are no territorial disputes. 


Predominantly mice should be fed fresh fruit and vegetables every day. Premium pellets and nuts can be an addition to use occasionally between meals to ensure they get a balanced nutritional diet.



Mice are prone to developing respiratory infections and growths. Growths can be hereditory; the best way to keep your mice healthy is to ensure they are active and receive a good diet every day. We at Pet City recommend using non-dusty pelleted bedding and keeping your mouse's enclosure in an area with good ventilation.



When handled from a young age, mice can be well-tamed and will put up with being picked up. As they are naturally very skittish, mice require to be handled every day by their owner to ensure they remain comfortable with being picked up. Never pick a mouse up by the tip of their tail as this can hurt and be quite scary. 


Oral Care

The teeth of a mouse are constantly growing. This makes chewing a natural behaviour. It is important to provide a pet mouse with chews, varying in texture and type. This ensures their teeth don't overgrow and keeps them clean and healthy.
