I am not an expert in pet handling to answer this question. But from my experience, your right cat will automatically identify you and jump onto you with tender affection. This is true for adult cats. But kittens do not do like this. You have to select the kitten you like by its playfulness, color, voice etc. But in case of dogs, it is very difficult as no dog will jump onto you with friendliness. All dogs wag their tails and be friendly if you are friendly towards them. The ultimate choice depends on your taste purely. Experience also may help.
