Is My Cat Sleeping Too Much? The Honest Answer
Cats are champion sleepers. Here's how to spot when extra sleep is illness in disguise.
How much sleep is normal for a cat?
Healthy adult cats sleep 12–16 hours a day. Kittens and seniors push 18–20. Most of that sleep is light dozing — they wake instantly to a sound or smell. The cat-nap pattern is normal. The shift to watch for isn't the total hours — it's the depth and the personality change.
Sleep that's actually a red flag
Hard to wake. Sleeping in unusual places (under the bed, in closets, far from the family). Stops greeting you, stops responding to favorite sounds (treat bag, can opener). Eyes look glazed or half-closed for long periods. Less grooming. Hiding combined with extra sleep is a particularly strong signal — cats hide when they feel unwell.
Common medical causes
Kidney disease (very common in older cats). Hyperthyroidism (paradoxically — they're exhausted but restless). Diabetes. Anemia. Pain (especially arthritis in older cats — lying down feels safer). Infection. Dental disease. Cancer.
What to track before the vet visit
Hours sleeping per day vs. baseline. Where they're sleeping (favorite spots vs. hidden spots). Eating and drinking changes. Litter box changes — bigger or more clumps may mean kidney issues or diabetes. Weight loss is a major signal in cats — feel along the spine and ribs. Take photos of the litter box and a short video of your cat at rest.
