A cat's a cat, right?

Well, kind of, but sometimes it's easy to forget that they come in various shapes and sizes. Just ask Derek Krahn, a director for a non-profit big cat sanctuary in Texas, who recently witnessed his domestic kitty Baggy challenge a lion named Noey.

"Baggy," her owner called out. "You will lose!"

But she didn't listen.

Because Baggy's a courageous cat — who is probably grateful for that wire fence.

Krahn posted the cats' interaction on YouTube, noting that "Baggy the housemeow has always been a tough little cookie, but I never thought she was this degree of crazy." He added that their meeting didn't end on a sour note, writing, "All is well, everything settled, and her and Noey (the lion) are back on speaking terms."
