That thing about how cats think humans are big kittens is a myth, yβknow.
Itβs basically born of false assumptions; folks were trying to explain how a naturally solitary animal could form such complex social bonds with humans, and the explanation they settled on is βitβs a displaced parent/child bondβ.
The trouble is, cats arenβt naturally solitary. We just assumed they were based on observations of European wildcats - but housecats arenβt descended from European wildcats. Theyβre descended from African wildcats, which are known to hunt in bonded pairs and family groupings, and that social tendency is even stronger in their domesticated relatives. The natural social unit of the housecat is a colony: a loose affiliation of cats centred around a shared territory held by alliance of dominant females, who raise all of the colonyβs kittens communally.
Itβs often remarked that dogs understand that humans are different, while cats just think humans are big, clumsy cats, and thatβs totally true - but they regard us as adult colonymates, not as kittens, and all of their social behaviour toward us makes a lot more sense through that lens.
They like to cuddle because communal grooming is how cats bond with colonymates - it establishes a shared scent-identity for the colony and helps clean spots that they canβt easily reach on their own.
They bring us dead animals because cats transport surplus kills back to the colonyβs shared territory for consumption by pregnant, nursing, or sick colonymates who canβt easily hunt on their own. Indeed, thatβs why they kill so much more than they individually need - itβs not for fun, but to generate enough surplus kills to sustain the colonyβs non-hunting members.
Theyβre okay with us messing with their kittens because communal parenting is the norm in a colony setting, and us being colonymates in their minds automatically makes us co-parents.
Itβs even why many cats are so much more tolerant toward very small children, as long as those children are related to one of their regular humans: they can tell the difference between human adults and human βkittensβ, and your kittens are their kittens.
Basically, youβre going to have a much easier time getting a handle on why your cat does why your cat does if you remember that the natural mode of social organisation for cats is not as isolated solitary hunters, but as a big communal catpile - and for that purpose, you count as a cat.
