Okay...now that I re-read...
I'm glad you got the advice of the radio/tv. I do the same thing for Baby. Also, when she was little I had her in an Xpen with food, water, toys, and her bed on one side, and her pee pad on the other. That way she had everything she needed, and wasn't cramped in a little crate. Do you have her in a crate? I leave Baby home for a lot longer than 3 hours, so your furbaby is LUCKY!!
Baby is home from 7:45-3:30. Baby still cries when I leave, but she FREAKS out with happiness when I come home. She doesn't get mad. Maybe you should get another furbaby to keep her happy!?
