That is part of their appeal. These cats are not of show quality but they are every bit as adventurous and loving. All cats are natural hunters. Don't try and change this trait, it's useless. It is instinctual and cannot be unlearned.
Cats usually are solitary animals.
They could survive in the wild easily, as long as there is prey. Kittens are abandoned as soon as they are weaned. Half grown, they find themselves alone and on there own. In the wild this is a do or die situation and the kitten meets the challenge well. Hunting is a three-step process for the cat, stalking, pouncing, and bites.
