How do cats learn to interact with people? That’s called socialization - and it’s very important.
In many shelters, a big part of getting cats and kittens ready for the adoption floor is having volunteers and staffers play with them. That's because play - even something as simple as chasing a toy - helps socialize cats and get them ready to be happy, healthy pets.
When it comes to socializing your cat with other cats, proceed with caution. Kittens often get along well together and don't mind sharing space, but an adult cat that considers her living space her territory may react badly to a new cat or kitten entering that area. If you choose to have a cat visit your home, provide your own cat with a place where she can hide and feel safe if she isn't ready to interact with another cat.
We hope this short briefer helped you become more interested in the socialization of cats.
