When Does Rigor Mortis Start In Guinea Pigs?


Rigor mortis or the stiffening of the joints is a process that starts to occur shortly after death in most animals.

In guinea pigs rigor mortis usually starts to set in within 1-2 hours after death.

The process is caused by the lack of oxygen and energy in the muscles which causes the muscle cells to break down and release calcium into the blood.

This calcium then causes the muscles to stiffen and contract.

Rigor mortis is not painful but it can make the body very stiff and difficult to move.

After a few hours the muscles will start to relax and the body will become more flexible again.
