From zoomies to zzzs: why do cats sleep so much?

When it’s time to chase a laser pointer or pounce on a rubber mouse, cats are all energy. But once they’ve found the sunniest spot in the house, good luck rousing them from their feline slumber. On average, cats doze off for a whopping 13 to 16 hours per day. These sustained snooze-fests aren’t a sign of laziness but rather a reflection of cats' unique evolutionary biology and their individual health needs. Read on to learn why these lengthy catnaps play a crucial role in your kitty’s overall well-being. The biology behind cats' sleep patterns Cats are obligate carnivores, meaning they need to get most of their nutrients from high-protein meats. As a result, cats are some of the most skilled predators in the animal kingdom, a role they've perfected over millennia. One study found that cats have contributed to the extinction of at least 2 reptile species, 21 mammal species, and 40 bird species, accounting for 26% of all known contemporary extinctions in these species groups. Their meat-heavy diet plays a major role in their sleep patterns. After a protein-rich meal, cats often experience a surge of the amino acid tryptophan, which leads to the production of serotonin. This naturally occurring brain chemical serves as a mood stabiliser and brings about feelings of contentment and relaxation. This all sets the stage for a good snooze. Cats’ ancestors were nocturnal hunters, a trait that modern-day domestic cats still exhibit, although to a lesser extent. The tendency to doze during daylight hours and become more active as dusk falls is a natural rhythm ingrained in their predatory DNA. The sleep-wake cycle of cats is actually regulated by the same light-sensitive hormone, melatonin, that governs human sleep. But cats have a quicker sleep cycle, transitioning from deep sleep to REM sleep faster than humans. This allows them to be well-rested yet ready to spring into action at a moment's notice. The importance of sleep for cats Sleep is fundamental to your cat’s health and well-being. Here are some of its myriad functions: Physical health Sleep is crucial for your cat’s physical health on multiple levels: Mental health Sleep is just as important for your kitty’s mental health, including: Cellular repair and maintenance Sleep also serves as a kind of internal kitty tune-up. Sleep is a cornerstone of a cat's holistic health. Each snooze session is a step towards maintaining their physical vigour and mental acuity. So the next time you see your feline friend curled up for a nap, remember: They’re just taking care of their overall well-being. Factors affecting cats' sleep duration Cats, like humans, have various factors influencing how much they sleep. Understanding the various factors affecting your cat's sleep can help you make sure they’re getting the rest they need. It all comes down to maintaining a comfortable sleep environment, a balanced diet, and regular check-ups to monitor their health. When should you be concerned about your cat's sleep habits? While it's normal for cats to sleep for long hours, there are certain signs that might indicate a problem. Take note of any sudden changes in your cat's sleep pattern or behaviour. Here are some signs that should prompt a visit to the vet: Being observant and proactive in monitoring your cat’s sleep and overall behaviour will help them stay healthy, especially if you promptly take any major concerns to the vet.
