vCat

A virtual cat that lives on your home screen.

vCat example application (with source code - see below) that implements a simple widget and service.

If you ignore that cat widget, it becomes needy and meows. If you pet the cat, it purrs.

vCat is a home screen widget only and not a regular application, you will need to add it to your home screen for it to do anything.
