Musing about beauty

Sitting on the bus it occured to me that human eyes probably look very ugly to other mammals. Normal mammalian eyes do not show the white except if the animal is distressed. Maybe to other mammals we look permanently distressed. Or maybe ideas of beauty are not based on our own species. Think of fur, fur is deeply attractive to humans even though we don't have it ourselves. People are often repelled by pink animals that aren't furry, think of sphinx cats and rats' tails. I am left without a conclusion.
