Pet Sleep Needs CalculatorPets sleep a lot more than people expect — adult dogs average 12–14 hours a day, adult cats 12–16 hours, and senior pets often 18+ hours. Too little or too much sleep can both signal problems. This calculator gives a personalised sleep target based on species, age and activity level.
How this calculator works
The calculator uses age- and species-based norms: puppies and kittens 18–22h, adults 12–16h, seniors 16–20h. Active and working pets sleep less by 1–2 hours; very low-activity pets often sleep more.
Frequently asked questions
Why does my cat sleep so much?
Cats are crepuscular hunters — biologically wired to nap during the day and be active at dawn/dusk. 14–16 hours of sleep per day is completely normal.
My dog suddenly sleeps a lot more — should I worry?
Sudden changes in sleep can signal pain, illness or hypothyroidism (especially in dogs). If lethargy lasts more than 48 hours, see a vet.
