It is not cruel to bring in a feral cat if the cat has gotten used to you and starts to love you.
As long as it's a feral and stray cat and not somebody's pet it's okay to take in a stray cat or feral cat.
I've taken in a feral cat and stray cats and they've always become really good companions.
I do let them go outside when they want as I would not want to be cooped up in the house and keeping them in the house all the time and never letting them outside is cruel but taking in a feral cat or stray cat itself is not cruel.
The animal that eats cats are lions, tigers, owls, eagles, bears, mountain lions, wolves, foxes and coyotes.
Dogs also can kill and eat cats and in the wild, snakes such as pythons have also been known to prey on and kill and eat cats and even crocodiles and alligators can also eat cats.
Cats originated in the Middle East's Fertile Crescent, around 10,000 years ago.
Domesticated cats that originated in the Middle East's Fertile Crescent around 10,000 years ago, originated as wildcats were drawn to the abundant rodent populations around early human agricultural settlements.
And the earliest evidence of human and cat companionship is a 9,500 year old burial of a human with a cat on the island of Cyprus, which indicates transportation by boat.
The domestication of cats we know today was a mutually beneficial although not fully intentional process.
And early farmers stored grain, which also attracted rodents like mice and rats and the rodents in turn attracted wild cats who ate them.
And the availability of prey near human settlements also likely led to cats becoming accustomed to humans.
A 9,500 year old burial in Cyprus also shows a human and a cat buried together, and the cat's presence suggests that the cat was brought to the island by boat.
Genetic analysis also confirms that domestic cats also descended from the Near Eastern wildcat "Felis silvestris lybica".
Cats also spread with humans along trade routes and they were also very useful on ships that were transporting of grain from the Near East.
Cats, in the family of Felidae also first appeared in Asia around 10 to 15 million years ago, with their evolutionary radiation beginning in Asia during the Miocene epoch.
Modern domestic cats, although originated from the Near Eastern wildcat subspecies, "Felis Silvestris lybica" and were first domesticated around 10,000 years ago in the Fertile Crescent, which is a region in the Middle East.
