My fur is silky smooth, and I'm outside a lot! I think it has to do a lot with the food, and also, if the cat go outsdie, where they go! My uncle Thomas spend most of his day hunting in the forrest, and his fur is quite often "thick" (as in a bit oily and you feel dirty after petting him)... he gets good cat food and fresh bolied fish (could possible have something to do with the fish too...?)
