My lovely wife, who receives every single catalog in the known universe, just informed me that she would be decorating our home with the following: a Ginger Tabby Sculpture. Described as a "lifesize feline" that is "limbering up, prepping to put in a long day's worth of work as a doorstop or house pet...requires no feeding and won't sharpen its claws on fine furnishings." I would add that this is a perfect alternative to offer to the young'uns when they ask you for a pet. This thing is a tad creepy, so maybe they'll be afraid of animals from now on.
More of a dog person? Pick up a West Highland Terrier Statuette. It's less lifelike, but also less expensive. And less creepy. But not by much.
P.S.: My wife just read this and asked that I point out that she's just kidding. She actually has very good taste in furnishings and also despises cats. The part about the catalogs, however, is true.
