I recently played with the TechPet (Bandai). If you don't have a real pet and want one, this might be something you'll be interested in trying. You interact and play with your pet using a free app downloaded to your iPhone or iPod Touch.
The TechPet has fun games and items your pet can play with. There is a musical game where you have to match up the colored star with the tune and another game where you have to move things off his face into his dog bowl without waking him up.
Every day, you feed and play with your pet and take care of him. Sometimes, he gets dirty, and you need to clean him, and other times he gets sick and a bubble pops up which tells you what you need to give him so he can get better. You can also teach your pet to sing, dance and sit. His tail wags, and his head and paws move to your command.
Some of the great things about this pet are that you don't have to walk it, and you don't have to clean up after it. But, if you want a fluffy, cuddly pet, then this pet is not for you.
I recommend this pet for kids ages 10 and older. The TechPet is also a speaker for your iPhone or iPod touch.
