I'm a member of site about cats and several have similar games for their cats. It's too cute!  It does keep them entertained.

I don't have an iPAD, but I've been keeping my eyes open for such games that can be run on my mini laptop PC.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
