Pets spend a large portion of their lives asleep, yet what happens during that time has long fascinated researchers and owners alike.
Subtle movements, vocalisations, and changes in breathing during sleep have led scientists to explore whether animals experience dreams similar to humans.
Research into animal sleep patterns shows that many pets cycle through different sleep stages, including periods linked to memory processing and brain activity.
While animals cannot tell us what they dream about, studies of brain waves and behaviour offer clues about how sleep supports learning, emotional regulation, and overall wellbeing.
Understanding how pets sleep can help owners recognise what is normal, when to let sleeping animals rest undisturbed, and when changes in sleep patterns may signal a concern.

Sleep behaviour can vary by species, age, health, and environment.
Consult a qualified veterinarian if you notice sudden or concerning changes in your pet’s sleep habits.

REM Sleep Reveals Dreaming In Pets
Your pet cycles through different sleep stages just like you do.
During Rapid Eye Movement (REM) sleep, their brain activity mirrors patterns seen when they’re awake and alert.
This phase typically occurs about 20 minutes after falling asleep for dogs.
Brain scans show that pets process information during REM sleep, suggesting they’re replaying daily events.
Cats and dogs spend roughly 10 to 12 percent of their total sleep time in this dream-rich phase.
Puppies and kittens actually dream more frequently than adult animals, possibly because their developing brains need extra processing time for all the new experiences they encounter each day.
Twitching Paws Signal Active Dreams
Watch your dog’s legs move like they’re chasing something invisible.
These adorable movements happen because the brain temporarily paralyzes major muscle groups during REM sleep, but smaller muscles can still twitch.
Your pet might be reliving their favourite game of fetch or pursuing that squirrel from the morning walk.
Cats display similar behaviours, sometimes extending their claws or flicking their tails while sleeping.
These physical signs offer a window into their dream world.
Younger animals tend to show more dramatic movements because the part of their brain controlling muscle paralysis during sleep isn’t fully developed yet, leading to more visible dream activity.
Vocalizations During Sleep Are Common
Soft whimpers, quiet barks, or gentle meows can escape from your sleeping pet.
Dogs might make running sounds or excited yips, while cats occasionally chirp or purr during their dreams.
These vocal expressions suggest they’re experiencing emotionally engaging scenarios in their sleep.
Most sleep sounds are completely normal and nothing to worry about.
However, loud or distressed vocalizations could indicate a nightmare or discomfort.
If your pet seems upset after waking, offer gentle reassurance with calm words and soft petting.
Some breeds are naturally more vocal during sleep than others, so getting to know your individual pet’s sleeping habits helps you distinguish normal dreaming from potential problems.
Research On Rats Supports Pet Dreaming
Scientists at MIT studied rats navigating mazes and then monitored their brain activity during sleep.
The research revealed that sleeping rats replayed the exact same neural patterns they exhibited while awake and exploring.
This groundbreaking study provided solid evidence that mammals process and potentially dream about their waking experiences.
Since rats share similar brain structures with dogs and cats, researchers believe our pets likely dream in comparable ways.
The study showed that animals don’t just rest during sleep but actively consolidate memories and learning.
This finding helps explain why proper sleep is so crucial for training new behaviours in pets and why well-rested animals learn faster.
Pets Likely Dream About Daily Activities
While we can’t ask our pets what they dream about, scientists believe their dreams reflect everyday experiences.
Dogs probably revisit moments like playing with their favourite toy, greeting family members, or exploring interesting smells at the park.
Cats might dream about stalking prey, climbing furniture, or batting at dangling objects.
Each pet’s dreams are likely as unique as their personality and daily routine.
A working dog might dream about herding sheep, while a lap dog could dream about cuddling on the couch.
The content of their dreams probably changes based on recent memorable events, explaining why an exciting day often leads to more active sleep with increased twitching and movement.
Sleep Patterns Vary By Species And Age
Dogs sleep between 12 and 14 hours daily, while cats can snooze up to 16 hours.
Puppies and kittens need even more rest, sometimes sleeping 18 to 20 hours as their bodies and brains develop rapidly.
Older pets also tend to sleep longer but may experience more fragmented sleep with frequent waking.
Size matters when it comes to sleep duration and dream frequency.
Larger dogs typically have longer, less frequent dreams compared to smaller breeds who experience shorter, more frequent dream episodes.
Understanding your pet’s normal sleep patterns helps you recognize when something might be wrong, such as sleeping significantly more or less than usual, which could signal health issues requiring veterinary attention.
