Selling and buying cats and dogs is prohibited in Islam. You can however give the cats as a gift but not sell them.

We bought a cat from a pet store here in Riyadh around an year ago, and now mashaAllah it has delivered 4 beautiful kittens, subhanAllah! There is a friend that is interested in buying one of the kittens. This issue came up, when another friend in th group said it was haram. This confused me. please i would appreciate your response as soon as possible.
