The Pet Master is a PDA, not for pets but to organize them. Instead of cluttering up your calendar or PDA with the appointments and play dates for your pet, you can store them separately, along with important phone numbers, like the vet. It has plenty of information about both cats and dogs, so it's great for all pet owners. The Pet Master has an alarm that will remind you of any scheduled events, a built-in pet shopping list and health facts, a list of pet-friendly hotels for traveling and emergency numbers - all pet-related, of course. There is even a frame built into the case which will allow you to tuck in a photo of man's best friend. It's only $29.95 and, in addition to doing something good for you and your own pet, a portion of the proceeds from each sale is donated to an animal charity.
