Instruction
1
To learn how to distinguish a female from a male, consider the sexual characteristics of animals, for example chinchillas. The same method can be used and the choice of hamsters.

2
Take your animal in the hands, upper torso and head put on your palm, and hold with the thumb of that hand. The back part to hang freely. Lightly support it with your other hand.

3
Now go on to study the external genitalia of the animal. At first glance they are very similar. Even the adult males you will not be able to detect the eggs, which are hidden under the skin. So look closely at the distance between the urethra genitals in the animals and their anus. Anus chinchillas, and other animals is located closer to the tail. And then comes the penis of the male urethra or the female. If the distance is almost imperceptible, it seems that the two holes a little if not merge, then it's a female. They have the anus and urethra very close to each other.

4
If between the holes there is a pretty noticeable gap, then it is male. Males chinchillas distance between the anus and the sexual organ is about 3-4 mm.

5
You can also look to an adult. Sometimes a female appears larger in the male. But this symptom may not always be accurate. There are males of considerable size.

6
The behavior of animals is also unlikely to identify their gender. Is that before mating, the male performs a hopping motion, as if trying to jump onto a female. But it also does not give a 100% guarantee β sometimes very frisky females that jump is exactly the same.
7
Usually in a pair dominates the female. She is more active, more mobile. But it all depends on the particular species, its temperament and habits.
8
But the color to determine the sex of your animal just will not succeed. Chinchillas do not have differences in color, as expressed, for example, a bird or some fish.
