Standridge, what type of lion is it? Because that is also an important factor. For example, a Volitans lion may very well eat the clowns someday IF he isn't fed enough and is feeling frisky one day, whereas a zebra, fuzzy, or fu manchu lion probably wouldn't attempt it with full grown clowns.
Part of why I'm getting a Fu Manchu. I don't want him to ever get a bug up his butt and go after my pretties. LOL
Someone stop me! Please! But... not just yet...
