When rigor mortis occurs and how long it persists depends on the temperature of the animal's body as well as that of its surroundings.

Owners may or may not encounter this phenomenon when their pets die.

It is not the contraction of muscles after death but a chemical reaction that results in the hardening of protein filaments in the muscle fibers within 6 to 12 hours and then relaxes those muscles again in 18 to 36 hours.

How long does is take for rigor mortis to set in for hamsters and how long does it last for because im not sure if my hamster is dead or not?

Rigor mortis in hamsters typically sets in within 1-3 hours of death and can last for about 12-24 hours before the body relaxes again. If you're unsure if your hamster is dead, look for other signs such as lack of breathing or heartbeat, lack of response to stimuli, and a lack of body warmth. It's also a good idea to consult a veterinarian for guidance.


How do hamsters look like when they die?

It depends on how long they have been dead. If they just died, they look just like they do when they are alive. After a bit they become stiff and lose body heat. Basically, they will be cool and hard if you touch them. If you are concerned your hamster may be dead, they best thing to do is try to gently roll it with your finger. If he is just sleeping, he will probably jump up pretty quick.


How do you know how long a cat has been dead?

When a creature (of any kind) dies, certain processes take place in its body. Its blood is no longer being pumped through its veins, and so coagulates (clots), eventually drying up completely. As the blood dries the creatures muscles contract and stiffen. This process is called Rigor Mortis. It causes the body to go stiff, hence the slang name for corpses. The process of Rigor Mortis in humans can take several hours to complete, depending on the persons condition before they died, and the reason for their death. In smaller animals it generally happens faster, as there is less blood to dry up. A cats body will usually be stiff as a board within an hour. The rigidity will give some indication as to how long the cat has been dead. If the cat has not been dead long enough for Rigor Mortis to set in you can estimate its time of death by the temperature of its body. A body this size may remain warm to the touch for around 30-45 minutes. After Rigor Mortis has set it becomes harder to determine a time of death, and the methods of doing so become increasingly complex and expensive. Proceedures such as these require a trained pathologist or mortician and a sterile laboratory. Another method that is used for bodies after a few days is to look at whether there are any fly eggs, larvae(maggots), pupae or evidence of these hatching. Each of these stages has a known timeframe (that may be temperature dependent).
