Also something related I never came to grips with: cat's breath = the stench of a thousand decaying corpses. Licks fur constantly. Fur = the smell of springtime itself.
My (unfortunately late) void had a scratching post with the top level just at my nose height, so whenever he lolled around there I made a point of taking a deep breath of fluffy freshness.
I have owned many cats, and I have huffed deeply of them all.
Cat fur, cat toes, cat bellies, all have these unique and wonderful scents that are probably more connected to our emotional connections to them than the actual nature of the scent itself. This should teach us a lot about social conditioning and our senses.
