For rigormortis to fully set in, it takes approximately 24 to 48 hours. For smaller animals, like squirrels, it may take less time.
Provided there were no electrolyte or musculoskeletal abnormalities prior to death, the carcass should be in full rigor within 12 hours.

How long it takes rigor mortis to set in depends on the size of the dog. The stiffening of the muscles usually begins within three hours of death and will affect small dogs much more quickly than large dogs.
The amount of time it take for rigor mortis to set in depends on the size of the dog. Normally, rigor mortis takes 12-24 hours to set in after a dog has died.
12 hours________Rigor mortis usually starts 2-4 hours after death but take a full effect within 6 to 8 hours. It depends on several factors like the genetics, the level of fitness of the person and the level of physical activity the person has undertaken before death and as you said, temperature has an effect too.
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.
A cat that has died will not be breathing, moving or responding to you, and depending how long the cat has been dead might be a little stiff from rigor mortis from setting in.
The severity of rigor mortis can be used to estimate a time of death. Shortly after dying, the muscles lose their permeability of calcium ions in the muscles and the muscles as a result stiffen. It can take a few hours for rigor mortis to fully set in.
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.
Much more quickly than in humans. I'm not a professional in either human or animal fields but here are some things that I do know: The smaller the (mammal) animal, the faster the respiration and the faster the heart rate. Rigor mortis is a process of muscles contracting because the energy production system is powered by oxygen. Logically, this means that when a small furry animal stops breathing, the oxygen will be lost from their systems more quickly than in a big animal, and so rigor mortis will be quicker. My cat died yesterday and it took less than two hours for rigor mortis to set in, from last time seen up and walking around to when I got home from school and found him under the couch. While I worked at the zoo last summer, I dealt with many dead animals- for a baby caribou, it took closer to four hours, for pygmy rabbits, less than one. I find the logical processing of the situation sometimes takes away the hurt.
Rigor mortis typically sets in within 2-6 hours after death, peaks around 12 hours, and generally dissipates after 24-48 hours. The duration can vary based on environmental factors and the individual's health and muscle mass.
