Ligers exist. They breed them, though not that often. They're freaking huge. Damn...that is one big pussy cat.
If I remember correctly, ligers are sterile so they can't have children. Something about their genetics not being perfectly compatible. I think mules are the same way(combination between a donkey and a horse FYI).
Yep, ALL mules are sterile, whether male or female. Though, on Wikipedia, it says that females may be able to carry offspring...not sure about that though...
