Kittens nibble on our toes for a very adorable reason - it's part of their natural hunting and play instincts.
As predators, kittens are biologically wired to attack moving objects, and our wiggling toes or feet under a blanket trigger this innate behavior
When kittens nibble, it's often a playful behavior as they practice their stalking, pouncing and biting skills.
Kittens may gently mouth or nibble on toes as a way to play hunt and hone their predatory abilities. It's their way of engaging in a fun game.
Kittens also learn bite inhibition from their mother and littermates. When they bite too hard, the other cats will yelp or stop playing, teaching the kitten to be gentler with their teeth
While kitten nibbling is normal and cute, it's important to redirect this behavior to appropriate toys to prevent the habit from continuing into adulthood when the bites can become more painful
Providing plenty of interactive play sessions and chew toys gives kittens an outlet for their hunting instincts.
