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.

∙ 13y agoIt depends upon the pet. Rigor mortis occurs within hours of death, and eventually fades within days. It occurs as a contraction of muscle fibres due to a chemical change, and is gradually reversed by decomposition of the stiffened tissues.
For smaller animals, rigor mortis can set-in much more quickly than for larger animals.

∙ 16y agoIt is because a chemical change takes place in the muscles that makes them become stiff . It is one of the signs of death. It is referred to as Rigor mortis. Pallor mortis, algor mortis, rigor mortis, livor mortis and decomposition are the 5 signs of death in order.

Wiki User
∙ 14y agoThis is called Rigor Mortis. Because the body is no longer breathing and taking in oxgen, respiration ceases. The body's usual energy pathways can no now longer function as normal - muscle tissue will contract, but without the usual supply of energy, they are unable to relax. The body therefore stiffens.
Sometime later, decomposition will break down the muscle tissue enough so that the body will become flexible again.
Wiki User
∙ 6y agoWhen a muscle contracts, temporary bonds form between the muscle filaments. This 'cross-bridge' requires energy to break. After someone dies, respiration will come to a halt. Without oxygen, the body will first exhaust its stores of glycogen, before ATP, the body's 'unit' of currency, can no longer be produced.
Once the ATP runs out, the muscle tissues are unable to relax, and rigor mortis sets in. After about 48 hours, enzyme activity will break down the muscle tissues enough for those linking cross-bridges to degrade, and the muscles will then be able to relax.

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).
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?
if it is cold and stiff it is dead it doesnt take long you'll smell it soon.
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.

Can i become executor of an estate after my father's death?
There is no reason you cannot become executor of an estate as long as the court agrees. As long as you are 18 or older, you can serve in that capacity.
I've been told that it takes 3 hours for rigor mortis to begin If a body was stiff to the extent that picking up and moving the body did not alter it's position about how long have they been deceased?
Well that depends on the temperature of the area where the body is!
How long does a body stay cold after death?
Forever. No cell action = no heat produced.
How long does it take for your body to become used to birth control?
One month.
How can body temperature determine the time of death?
it is the temperature of the liver that determines the time of death (how long a body has been dead). that's why the medical examiner sticks a meat thermometer into the liver.
How long before death does body temperature start lowering?
Actually, the body temp does not begin to lower until, either immediately, or maybe 5 minutes post-mortem, which means after death.
