Mouse

Remember

A pet mouse is lively and easily tame by gentle handling and is inexpensive to keep. However, mice are more active at night and do remember that male mice smell.

A pet mouse needs

• Companionship - to be with other mice and people
• A balanced diet of mixed grains and a small amount of fresh fruit, vegetables and bread.
• A salt/mineral lick
• To have a constant supply of fresh drinking water from a drip-feed bottle with a metal spout
• A piece of hard wood to gnaw
• A cage - 45 x 30 x25 cm high (suitable for three mice)
• Shredded white paper or fresh meadow hay in its cage, with a clean layer of sawdust of woodshaving underneath
• A cage with hiding places and a nestbox with a little fresh meadow hay or paper bedding
• A clean cage - cleanliness is important. The bedding must be changed weekly
• Plenty of exercise. The cage should be fitted with a solid exercise wheel and ropes and ladders for the mouse to climb on.
• To be kept indoors at an even temperature away from direct sunlight
• Careful and sensitive handling
• To be taken to a veterinary surgeon straight away when it is unwell
• To be looked after at holiday times
• Your time and interest for the rest of its life
