Was that a little bit too easy ?
No, not really, though it helped that with all the animals in the question, the 'king' of animals soon came to mind, and I've always liked crosswords and other forms of wordplay.
Having said that, I'm going to set a number puzzle!
1 1 1 = 6 (That's three ones, not one hundred and eleven)
Make the above equation correct by adding some common arithmetic notation to the left side.
