Cats often continue to knead from kittenhood into adulthood, and the behavior remains for many reasons!
It’s believed that cats associate the act of kneading with the memory of getting milk from their mothers during kittenhood, so, with that in mind, some believe that cats may knead to seek comfort and relaxation. So, it’s no surprise that it is almost always on a soft, plushy surface when they do knead.
Beyond that, cats may knead to mark their territory. Cat’s paws (and dogs, too!) have scent glands, so kneading different objects allows them to transfer their scent onto them. While this isn’t always the reason for cats kneading, if there are other animals in the household, this could be a plausible reason!
Do you notice your cat kneading after mealtime or at times that feel repetitive? It could be part of a routine they’ve created that helps them get settled in and relaxed. Maybe it’s after mealtime when they’re ready to settle in for a nap or before they lay down for bedtime — these are common times you might see your cat kneading to get a bit extra cozy in their space.
Kneading also resembles a cat giving a massage — sometimes that could be the case! No, they’re not massaging your pillows and blankets; they’re massaging their own little muscles. Pouncing around all day — or maybe sleeping in contorted positions — may lead to tired or sore feet and muscles, so there’s a chance that their kneading could be to give themselves a little TLC.
Some female cats may also knead when they are in heat and trying to attract a male mate. According to the Feline Medical Clinic, “Some female cats take to kneading the air while laying on their sides; This is an instinctual mating behavior signaling male cats they are “available.” Further courtship, however, is required before a female acquiesces to formal mating.”
