A breed of house cat is being bred to look like tigers. They'll be beautiful, I'm sure, but I'm in the camp that questions the ethics of breeding "designer" pets that will cost hundreds or even thousands of dollars. Millions of cats and dogs are put down in shelters every year for lack of homes. Purebreds are also subject to diseases resulting from inbreeding.
People have always bred for desired characteristics, whether in livestock or crops, but this is a far cry from breeding good mousers or even good pets. Designer pets are just another toy for the rich. I like my kitties far too much to just consider them accessories.
