While pocket pets can provide comfort, if you have the space and time for it, a dog or cat is most likely a better pet. These are pets who can actually learn and will grow more accustomed to you. Since they live longer, they will probably make better pets as well; you will not find them needing replacement as often.
Dogs and cats can often become members of the family and that is a very good thing in this case. Having an animal that looks forward to you coming home, as a dog will can be very rewarding. Cats, unless they are particularly moody, will also be happy to see you when you come home (unless they are asleep). Kittens, along with most dogs, are particularly playful. They will be very happy to respond if you offer a game to play together, and will sometimes even approach you offering to play a game.
It is, however, important that you remember that while you can talk to your pets, they cannot replace human companionship. They don't talk back. You can tell your dog or cat about your day or tell it how you are feeling but it won't be able to offer any words of advice. It won't be able to tell you that everything will be better, but it might lick your face. Sometimes, that is all that you need.
