1. Grumpy Cat left Maru in the dust in late 2012.
Even adorable box behavior is no match for Grumpy.
2. He surged past Simba too.
3. Keyboard cat is so 2009.
4. Lil Bub is way behind.
5. Felix has been on a downswing for a long time.
He never really got the Internet anyway.
6. Nyan Cat had a good run, but now it's Grumpy's turn.
7. Garfield put up a valiant fight, but Grumpy eventually won.
8. Colonel Meow was never really a contender.
This graph probably makes him really mad.
