I witnessed this on an additional message board: "I ran end the cat and also was horrified. I stopped the car and looked (for some unknown reason) right into my rearview mirror. The human body jerked number of feet up right into the wait (past the street I might see in mine mirror), about four or five times, yet the body to be lifeless. The head and limbs proper moved. What can make the human body jerk for this reason high like that? then it came to me. The cat to be trying to totally free himself indigenous the dead body. That course, I confirm the cat - it was stiff and most certainly dead ...."This person insurance claims rigor mortis to adjust in automatically with cats. Ns disagree. Space there any kind of vets roughly that could like come comment?

Rigor mortis manifests in cats at the same price that it wake up in all mammals - ~ a few hours. As soon as this occurs, muscles increasingly stiffen till the human body becomes stiff together a board. This state persists because that 12-20 hours prior to the human body becomes flaccid again and also begins come decay.The reason of rigor mortis relates to power supply in muscles. Muscles in reality use energy to relax, i beg your pardon they perform by break associations in between the actin and also myosin filaments that comprise muscle. When an animal very first dies, muscles room biochemically still metabolically energetic and therefore they have actually a prepared supply the energy and can break any links between actin and myosin.But, as time passes and also cells operation out the energy, this have the right to no longer be done and also the muscles "lock up". This is rigor. After another 10-15 hours has passed in this state, however, the cells and the contractile proteins start to rest down, which reasons the return to a flaccid state.In the question over the cat apparently jumped into the air number of times in spite of the fact that it was dead. The most most likely explanation is voluntary muscle activation initiated by waves of nerve discharges in the brain and spinal cord which can be triggered by physical trauma or together a an effect of oxygen deficit.Chris
