It can be quite nerve-racking to bring a new cat or kitten into your home and introducing them to your resident cat or dog. You should always keep in mind that cats do not need to be social creatures, this is quite different from pack-orientated dogs they can be happy without a social structure. Even though you wish to have another cat around, your cat is unlikely to feel the need for a companion.
However, how you introduce a new cat or kitten into your home and to a resident cat or cats can make a difference. It can be difficult to change behavior patterns once a relationship becomes violent or fearful and the cat feels threatened. So you will want to take things slowly with careful introductions to prevent excessive reactions.
