Contrary to common belief, most cats enjoy the company of other cats, because this is how they behave without human intervention. Think about what you see with mother cats and their kittens, or try to remember a time when you saw two cats interacting. Sure, perhaps not every moment was super zen. But did you ever see behaviors like grooming, playing, cuddling, or even simply looking out the window together?
This is why keeping cats and kittens with same-species companions is a great way to honor their true nature. When someone adopts a kitten, the ideal situation is that the kitten goes to a home that has another resident cat. However, keeping two kittens together is a way to ensure that each cat has a buddy without having to go through the lengthy introduction process
