Well,what else do you suppose they're wanting to do while you're at work all day? Via the New York Times, I learned that there is now a dedicated Internet radio station purely for pets. More from the Times:
"DogCatRadio.com, a new Internet radio station for pets. Now dogs, cats, hamsters and parrots can keep the anxiety, the loneliness, the restlessness at bay while their owners are out. It is radio just for them, live 17 hours a day, 4 a.m. to 9 p.m. Pacific time, and podcast for the rest of the 24 hours."
