A large percentage of American homes enjoy a pet as part of their family -- usually a dog or a cat or so. Some will pipe up with mention of their beautiful goldfish, perhaps a salamander or turtle, or perhaps even a horse. But today, we will deal with the cat and dog varieties.

Perhaps that pet has come with a marriage. Or maybe it was the arrival of children whose coming can bring about an animal adoption after some coaxing. Whatever the case, let's take a look at what is involved in living with a cat or dog. What is involved in such ownership? Who will take care of such responsibilities? How will these affect family life? These questions have to be considered.

As a person living alone, I can tell you a cat is the easiest (even though I sometimes treat Softy like a dog).

Yes, cats are easy, but they don't have the expressive eyes of dogs, and don't show their enthusiasm as dogs do, with welcoming barks, prancing around you, obviously delighted!

I guess I do have to admit, though I'm a cat owner, that dogs are smarter. My friend Dot Miller tells me their dog ran and got her husband when she had fallen and couldn't get up. No, I don't think a cat would do that.

The obligation part comes when you have to leave town. Usually you can find a neighbor or relative who will come in to feed the kitty or pup. Get them to promise a few pats, too. I also regularly take Softy, my indoor kitty, for a walk on the leash. So he gets some air. He has adjusted to that quite well and enjoys it. Often he stands at the door and clearly says, “Let's go out!” I also keep my lap available at home, for times he wants some “fellowship.”

If you like animals, accept the responsibilities -- vet and food expenses -- do get a cat or dog. I've found my pets to be very companionable and fun to have around.
