It appears that what we called separation anxiety may simply be frustration,” says Professor Daniel Mills, author of the study, published in the journal Plos One.
In fact, in their typical fashion, cats domesticated themselves.
All domestic cats are descended from the Middle Eastern wild cat (Felis silvestris), the "forest cat."
People didn't lure these first cats out of the forest; the cats themselves came into our barns, where many mice fed uncontrollably.
Therefore, cats do not need to form packs to look after themselves.
Because of this, they have highly developed possessive instincts.
All this makes domestic cats much more independent compared to dogs.
Wild relatives of cats hunt from ambush or by sneaking up on prey.
It is important for them to weaken their scent so that the victim smells them as late as possible.
In addition, dogs are descendants of wolves that overtake their prey as a result of open pursuit, so there is no need for them to camouflage.
