Not millions, but with the right site, such as the one recommended by dreamscape, it could potentially be quite profitable. People like these sorts of animal/pet related sites and with the name being memorable and catchy (though not necessarily for the intended reason, lol), it could do quite well. If you don't plan on building it out yourself, maybe you should contact a site such as ICanHasCheezburger.com and tell them of the possible site idea. Maybe they'd buy it from you as they could easily make money with it.
