Another Burger style out there scenario, and just to make things interesting, I put in some downsides to each:
The chef cat, while he or she specializes in seafood type dishes they're pretty adept at a wide variety of dishes. They don't clean up after themselves though. It's up to you to clean the dishes, and they're not careful about leaving messes.
The vocalist/instrumental cat is really good at singing, but they are also okay at playing instruments. If there was one instrument where the cat specializes in, it'd be the harp. Just because their claws would aid them in playing beautiful melodies. The only downside is that they like to play music at night too, since felines are nocturnal. So expect to wear earplugs or something of the sort to be able to sleep.
