Mice

Mice are reoccurring elements in the games, starting with the original Catz. They do not appear in any of the separate Dogz games, but will appear once both games are combined as in Petz II and beyond.

There are two mice that will appear concurrently, a white one and a gray one.

In the earlier games, the mouse hole was at the bottom of the Supply Case. With the introduction of Playscenes in Petz 3, they now live in the walls of in the Family Room but will also appear in the Back Yard and Playpen from the sides of the screen. The General Options menu allows for disabling Mice appearing with the Mouse Holes Closed option.

Mice can appear in South Seas Island.

Behavior
Mice can be lured out with cheese, though it isn't absolutely required to get them to come out and play. They will steal specks of Cheese or even Treatz off the ground until startled back into their holes by a Pet. If left to roam, mice will sniff their surroundings and occasionally groom themselves.

With Petz
It is debated if Catz can eat mice; there is anecdotal evidence but no concrete proof. It's possible players who report seeing their Petz eat mice could be getting them mixed up with Oddballz eating Grubz.

With the Player
Mice can be picked up the same way Petz can and can painted with the Paint Can and Brush.
