Interesting question. Cats apparently have "dichromatic" vision, and orange is among the colors that they basically can't distinguish from grey.
I have an orange male. He's awesome, and he doesn't leave anything on the table as far as cognitive ability goes. He's just very wrapped up in his important cat business that mostly resolves around territory, chipmunks and hanging out with his enemies.
My cat desperately meowed at me this morning to go outside to hang out with her enemies, which I denied her request. She brought a very much alive and unharmed chipmunk home the other day which was booking it around our great room until we corralled him outside with a broom. The live bird incident was even more dramatic. It’s like having a mischievious goblin living in your house. But she does keep the mice from coming in during the winter!
My parents' cat delivered a live baby bunny to the entrance hallways in the middle of my pre-wedding dinner. Once released the thing unfroze and zoomed under some baskets. It was an all-hands-on-deck exercise to corral both the terrified bunny, as well as the over-excited large dog who "wanted to get to know it".
I have similar stories with mine. Bringing live game into the house isn't mischief though. It's the highest praise a cat can express: as a trusted member of the pride, you're entitled to a share of the catch. You're also expected to notice the prowess.
