REPRODUCTION OF THE MOUSE
The color mouse has several cycles per year. The cycle is 4-9 days. Estrus lasts 12-14 hours.
Granivore, partly insectivore/carnivore: seeds, grains, vegetables, fruits (limited amount due to high sugar content), herbs and animal proteins. Fresh food, such as vegetables, herbs and fruit (to a limited extent) may be offered after slow habituation.
COMPOSITION OF THE MOUSE FOOD
- Crude protein (Rp): 12.5-18%
- Crude fat (RVe): 4-5%
- Crude fibers (RVz): 6-9 %
- Calcium (Ca): 0.4-0.7% - with excess phosphorus there is a risk of renal calcification 0.3-0.4% (Ca-F ratio: 1-1.5
HOUSING THE MOUSE
- in small groups
- a group of several females can usually be kept without any problems
- keep 1 neutered male with 1 or 3 - 4 females unneutered males should not be kept together (fighting for hierarchy)
POSITION OF THE MOUSE HOUSE
- no direct sunlight
- relative humidity 40 - 60 %
- elevated position
SIZE OF THE MOUSE HOUSE
- at least 80 x 50 x 80 cm (W x D x H) for 2 - 4 animals
- Free range is possible with tame animals under supervision
GROUND COVER FOR MICE
- good absorbent
- odor-binding, highly ammonia-binding
- low dust
- a high straw layer makes it possible to dig tunnels
- replaced regularly (strong odor)
ARRANGEMENT OF THE MOUSE CAGE
- several houses and hay or cellulose as nesting material
- connect multiple levels with stairs or hammocks
- climbing branch, clay or cork pipes
- gnawing wood e.g. Back to the ROOTS Gnawing root pleasure
- feed in sturdy clay or ceramic dishes (clean the dishes daily)
- drinking water in bottles or bowls on an elevation (change the water daily)
- running wheel
- bath sand
HANDLING A MOUSE
INDICATIONS OF DISEASE
- During the first days, colored mice need a lot of rest to get used to them.
- Color mice are suitable for children from about 10 years old under the supervision of their parents.
- Form a cavity with both hands and let the animal climb into it.
- Do not hold the mice by the middle or end of their tail.
Weight loss, reduced intake of food and water, altered dropping and urination behavior as well as a shaggy coat are, among other things, indications of a disease. Save Save Save Save
