A decorative mouse as a pet is a good option. It is not too difficult to master the care of this small animal, and it takes up little space. Zoologists advise keeping at least a couple of same-sex animals, as they need society. If you get a "boy" and "girl", then soon you can expect numerous offspring. To protect yourself from unnecessary trouble, you need to determine the gender of the mice before buying.
Instructions
Step 1
Try to determine the sex of a mouse 7-10 days old. At this time, the abdomen of the animal has not yet become overgrown with wool, therefore, secondary sexual characteristics can be observed in the female - two rows of nipples. They are well visible; after two weeks of age, the overgrown mammary glands can be felt. Accordingly, if a pet has no nipples, then you have a male in front of you.
Step 2
Flip the mouse belly up and pull the tail down slightly. Proceed with extreme caution, as the skeleton of mice is extremely fragile! Veterinarians strictly forbid holding the animal by the tail. Take a close look at your pet's anus and genitals. It is necessary to compare this individual with a representative of the opposite sex of the same age (if the sex of the latter is known). The distance between the two organs in females will be less than in males.
Step 3
Finally, the mouse can see the future paired male organs (testicles) in the form of dark spots. When the male grows up, his testicles and genitals will develop well. The structure of adults is reflected even in the gait - the male animal walks a little waddling. Determining the gender of the mouse will no longer cause you any difficulties.
Step 4
According to some lovers of domestic rodents, female and male mice can differ in their behavior. Upon direct examination of the genitals, the "girl" will withstand this procedure more calmly, and the "boy" will most likely try to bite you. One of the sex differences in mice is the pungent smell that males spread around them. Pets get along better with "friends". Males, on the other hand (especially if they are of the same age and not castrated), will certainly fight for leadership - even if there is no “lady” next to them.
