Can you toilet train a cat?

Ours cats will go into the cat pan, but the one cat always goes into a corner of the pan not the middle like the other cat does. Also, our cat pan can't have a lid, they won't go if is has one.

My step-mothers cat, has to be first in the cat pan after it's been scooped. He'll sometimes try to get in when you're in the middle of scooping it!

We once had a cat that just started using the toilet on her own, and we don't even know how or why she did it. We think that it might have been a monkey see monkey do thing.

It all really depends on your cat.
