kitten is simply another word for a baby cat
Kitten might just be a synonym for a baby cat, but it's so much more than that! Right now my kitten is purring and watching me type this.
Yes cats and kittens are known to be very social with humans
Were you aware that cats are the only species to self-domesticate?
I was not aware of that, I also love the big cat variety, they young are refereed to as cubs
