Can cats dream? This is a question that many people would like the answer for; there is so much interest in this subject that there are studies being done on whether cats can dream. The question arises from the fact that cats sleep so much, up to 16 hours a day for some cats.
When humans sleep they go through different stages of sleep, when they enter the REM stage of sleep, Rapid Eye Movement, this is when they are dreaming. This stage is called rapid eye movement because when a person enters this stage of sleep their eyes move rapidly back and forth as if they are watching a movie. We know that humans are dreaming during the REM stage of sleep because there have been many sleep study test to prove that this is the dream state for humans.
If you watch a cat when it is sleeping it will also reach a stage of rapid eye movement, you will be able to see their eyes darting back and forth under their eyelids. Dogs also have this same eye movement as they sleep. This leads scientist to believe that animals have REM sleep, and dream during this stage of sleep just as humans dream.
Cats will also move during REM sleep, which also supports the theory that they are dreaming. You will see a cat move its legs as if it is running, it will twitch its whiskers and nose while sleeping also. The main problem that researchers have in proving whether cats can dream is the fact that they cannot tell us what is happening to them while they are asleep. This leaves researchers, scientist, and cat owners just making the assumption that since cats also have a REM stage of sleep, that like us, they must be dreaming during this stage of sleep.
