Eh, any time someone ascribes motivations to animals, my butthole spasms.

The best that should be said is that the behaviors they exhibit are similar to the behaviors they exhibit for kittens or sometimes sick cats.

Somehow, somebody decided that meant they think we're bad hunters, and the idea took off because it's funny, but you can't know what goes on inside the thoughts of other humans reliably, much less other animals.

There's competing possibilities that the cats are showing off their kills to their social group, which is not only a common behavior when cats are young, but when they're mated, but you don't see people crowing about them bringing us food to get in our pants.

Overall, cats seem to treat us like other cats. Not exactly the same, but with less distinction than other domesticated animals. Horses, as an example, have a much wider distinction, for equally unprovable reasons.

My personal pet idea is that any sufficiently social animal, including humans, is instinctively going to seek out groups. They/we will negotiate the lack of a unifying language as best as possible, but with plenty of misunderstandings. It isn't so much that other animals see us as being the same as them. It's that they don't really have the need for the distinction; there's the in group (pride, pack, clan, whatever you want to call it) and out groups. When dealing with the family group, any animal will perform the same basic behaviors that their instincts tell them to.

Domestication just means that a given type of animal has developed or been bred to have, a stronger instinct for social bonding than wild animals, to the degree that they'll accept other species as family easier.
