Performances of chinchilla in estrus:

1. When chinchilla is in estrus, its activity level will increase significantly, especially at night. Keepers can often hear it jumping up and down. sound.

2. When a chinchilla is in estrus, its appetite will decrease rapidly, and it may take two days to finish the normal daily food. They also waste food by throwing uneaten food out of the cage or out of the food bowl.

3. When a female chinchilla is in estrus, she will often lick her genitals. When she smells the smell of a male chinchilla, she will drool urine. When a female chinchilla is in heat, her vaginal opening will split and become red, swollen, and a little secretion will flow out.

4. When a male chinchilla is in estrus, it will make a "coo" sound, which is the sound of the chinchilla in courtship. Because male chinchillas can mate all year round, keepers may hear this sound all year round.

5. If two chinchillas of the opposite sex are kept in a cage, the male chinchilla will lick the female chinchilla’s genitals after going into estrus, try to ride on the female chinchilla, and even have sex with the female chinchilla. Cats nuzzle each other to get close to each other.
