How Much Do Senior Cats Sleep?
Regardless of their age, cats tend to spend at least half of their days sleeping. And in their senior years, their number of rest hours only grows. Adult cats generally sleep 12–16 hours a day, whereas senior cats can sleep as much as 18 hours a day, says Catriona Love, DVM at Heart of Chelsea Veterinary Group in Seattle. Although this sleep schedule might seem indulgent—and even enviable to the busy pet parents who witness it—a cat’s sleeping style is different from the way people tend to sleep. Rather than sleeping deeply for hours straight, cats cycle through 20- to 30-minute bursts of deep sleep. In other words, they’re taking catnaps. This type of sleep cycle is necessary for a cat’s natural predatory state. Instead of one long night’s sleep, potentially leaving them drowsy later in the day, they maintain their sharp, predatory eyes by resting a little at a time. “Having more frequent sleeps allows them to be more alert and aware for more of the time when they’re awake,” Dr. Love says. As cats enter their senior years, their body requires more time to rest and recover. Several physical factors contribute to their need for extra hours snoozing, including “a natural decrease in energy levels, age-related physical changes, and a reduced metabolic rate,” says Bethany Hsia, DVM, co-founder of CodaPet. ,Some senior cats sleep so much they’re practically professional nappers. But how much sleep is too much? With guidance from veterinarians, we’ll walk through how to spot the difference between normal senior snoozing and potential health concerns, plus simple ways to support better rest for your cat at home.
