It doesn't all come naturally. Cats learn to hunt and strengthen their skills through observation, practice, and trial-and-error.
Kittens observe their mum's hunting strategies from a young age. They watch her stalk, pounce and prey, and their siblings become the first 'target.' Kittens also play amongst each other, practising their newly learned hunting skills.
As they become cats, the hunting instinct strengthens. They'll begin chasing insects and eventually work their way up to catching larger rodents such as mice. Sometimes, your feet under the covers may become prey too. Watch out.
