How to use the dog and cat normal sleep hours guide
Widely reported daily sleep is 12 to 14 hours for an adult dog, 16 to 20 hours for a puppy, 14 to 18 hours for a senior dog, and 12 to 16 hours for an adult cat aged one to ten. Pick the life stage, enter the hours your pet actually slept, and the tool shows whether that sits inside the range.
The comparison treats at or above the low bound and at or below the high bound as inside the range, so boundary values count as inside. Kittens and senior cats are described as sleeping more than adult cats, but no specific hour range could be verified, so that option asks you to enter a range agreed with your veterinarian instead.
Sleep hours swing with activity, room temperature and noise, and a single day is a weak basis for judgement. Falling outside the range does not by itself mean illness, and sitting inside it does not rule out a problem if your pet is hard to rouse or wakes often at night. Figures reflect October 2026.
