Several years ago, Jenkat changed how it did things and began partnering with iWin. They were just not making enough money from what I was told. They had planned on developing their own games more that were bigger and not "casual" games. That apparently didn't work out.
I just went to their site and the only thing left is the name and the purple cat logo. The copyright and support and everything else is iWin.
Another small developer/distributor bites the dust! That's just so sad.
