Rigor mortis can be affected by the size of an animal. A mouse for example as a very high metabolism and fast heart rate were as a elephant has a very slow metabolism and slower heart rate. The mouse's muscle would starve of energy faster then a elephants entering into rigor mortis faster.
There is a range of times that rigor mortis can set in over, but yes, in general the time frame is similar for humans and non-human animals.
Rigor mortis (literally "stiffness of death") is a natural process within the body after somatic death in which the skeletal muscles become locked in a contracted position. The carcass becomes rigid and unbending. Intoxication with a neurotoxin could affect the development of rigor mortis. For instance, tetanus toxin would cause the animal to be practically in rigor mortis at the time of death because it causes a spastic paralysis where the muscles are contracted during life. In contrast, botulinum toxin might cause the animal to have delayed rigor mortis or even to not develop a full rigor mortis because it blocks the nerves and causes a flaccid paralysis.
Rigor mortice is the (temporary) stiffening of joints after death. Animals do not die of rigor mortice.
Temperature does effect rigor mortis. Low temperatures slow rigor mortis and it is accelerated by high temperatures.
Rigor Mortis Sets In was created in 1972-11.
The duration of Rigor Mortis - radio - is 1800.0 seconds.
Rigor mortis is a build up of released lactic acid. Rigor mortis starts a few hours after you die, and causes your muscles to contract, or shorten, which is their natural state. After about 12 hours Rigor mortis begins to dissipate.

Rigor Mortis - radio - ended on 2006-03-02.
Short answer; yes.All muscles undergo rigor mortis at some time after death.
That is the correct spelling for "rigor mortis" -- a Latin phrase applied to the stiffening of muscle tissues after death.
Do not commence CPR if signs of rigor mortis or lividity are present.
