So i wanted to feed my cat some cheeseburgers...?

So I took my cat to McDonald's and they refused to sell me a Cheeseburger for my cat! Don't cats say "Can I haz a Cheezburger" like that website? Also if McDonald's is refusing to sell me a Cheeseburger for my dear ol' cat, do you think they would give me a Filet O' Fish instead?
