The general wisdom is that cats dream for the same reason as all mammals. Sleeping helps us to process experiences and information.
Everything from playing with their owners to contact with other animals or humans or time spent cuddling. Cats often use sleep to recall and organize the events of their day.
The most significant indication of a cat dreaming is when its body is in a completely relaxed and slack position.
There is no clear evidence to support that cats have nightmares or bad dreams.
Again, like their owners, cats may have trouble sleeping and reaching that all-important REM stage. Cats can suffer from insomnia as well as sleep apnea.
