Has anyone ever heard of this?

It's called Catz, and there is also a Dogz program.
I had the Catz game for several years before the program crashed for good. I had loaned a copy of the cd to a friend's mother; she loaned it to someone else and it got lost.

You can select a puppy or a kitten, and then watch it grow.
You have to pet and give them attention everyday when you are online, or the Pet will run away.
I had that happen once and it was not fun. ( It was my fault - I had 9 Catz at one time!
I later brought it down to three catz and that worked fine.
You can pet them, give them treatz, select toys for them to play with, plant a garden for them to play in, and their are many outdoor scenes for your petz and you to enjoy.
I'm going to buy another cd of this program; I really did enjoy it!
