The Science of Pet Sleep: Do Dogs and Cats Dream?

Sleep plays a vital role in your pet’s emotional and physical health. Dogs and cats experience complex sleep cycles similar to humans—including REM sleep, the stage where dreaming occurs. Understanding how pets sleep and what their dreams may reveal helps you support their wellbeing and create a calmer home environment.

Key Takeaways

• Pets experience REM sleep, the stage associated with dreaming.

Typical Sleep Patterns

• Dogs: 12–14 hours per day, more for puppies.
• Cats: 12–16 hours per day, often in short cycles.
