The main reasons why hamsters play dead are as follows:
Self-Protection: Playing dead is an instinctive behavior of self-protection for hamsters. It usually happens when they sense threats or get frightened. This behavior can help them avoid potential harm.
Being Frightened: Hamsters are rather timid. Once they are severely frightened, they will play dead to protect themselves. This kind of reaction is a self-protection mechanism in their nature.
Deep Sleep: Although the time when hamsters are truly in a deep sleep is quite short, in some cases, they might sleep so soundly that they seem to be playing dead.
Nervousness: When hamsters are separated into different cages or enter a new environment, they may feel nervous, and this nervous emotion can also lead them to appear to be playing dead.
The manifestations of hamsters playing dead usually include having a stiff body, remaining motionless, and keeping their eyes tightly shut. These behaviors make them look like they are "dead", but in fact, they are not in danger of losing their lives.
How to Tell Whether a Hamster Is Truly Dead: You can tell by gently touching the hamster's body and checking its breathing and heartbeat. If the hamster has indeed passed away, there will be no responses in these physiological indicators.
By understanding these reasons and manifestations, we can better understand the behaviors of hamsters and take appropriate measures when necessary.
