From Takashi T. Hamada:
NekoOnDesktop is a cat-breeding application. You can breed your virtual cats, on your desktop! Once NekoOnDesktop is launched, cats run, sleep, eat, and play with you on the desktop. Sometimes they are hungry, sometimes get sick. You can take care of them with various items, such as milk bowl and shower.
The kittens are cute and customizable. You can also turn them off.
The sounds and distractions would drive me batty, but my kids thought they were cute enough to keep playing. If you like electronic pets, you'd like this game.
The Neko cats are cute and very interactive. You can set their personalities and have many at the same time. But the constant action and sounds are distracting. If you use your computer for work, this isn't the right program to install. But for kids or a family computer, they'd be a fun addition.
