Fancy Mouse - Health

Health

A healthy fancy mouse will live on average 18 to 30 months, depending on genetic predisposition. Like most mammals mice are susceptible to mites, ticks and other skin parasites, as well as intestinal parasites. The cage should be cleaned regularly, and preferably treated with anti-mite spray. Mice are particularly sensitive to drafts and may pick up colds and other flu-like conditions. Mice can also over-groom when stressed, leading to skin irritations and fur loss. Older mice are susceptible to tumors, especially breast cancer in females as the mammary tissue is distributed around much of the body. Persistent problems should be referred to a veterinarian, although finding a vet with experience in treating mice can be difficult.

Like people, fancy mice can become obese if they overeat and do not get enough physical activity. This can lead to them developing life-threatening cardiovascular disorders and diabetes as well as arthritis. Activity aids such as tubes and wheels are great for ensuring mice get enough exercise, as well as mental stimulation. Mice also love to climb, and a wire cage with horizontal bars is perfect for this. A mouse set loose for exercise should be carefully observed, as they tend to scurry into a hiding spot and can be difficult to retrieve.

As rodents, mice must gnaw to keep their incisors from growing too long. Overgrown teeth can cause occlusion (blockage) of the mouth, which in extreme cases can lead to starvation. Hard foodstuffs, small pieces of wood or specially-prepared blocks can suit this purpose, although some mice can grind their teeth together ("bruxing") to keep them short. In rare cases a mouse may not be able to gnaw effectively, either from malformed incisors or jaws, and so its teeth must be trimmed by a vet.

Mice self-groom and do not need to be bathed, unless they have a skin condition which requires special treatment.

Also, like people, mice can get diarrhea. For humans in developed countries with access to clean water, this is usually not a life-threatening condition. For mice though, it can be. Once a mouse gets diarrhea, since it is so small, it can very easily lose too much liquid, dehydrate, and die.
