As well as being a remarkably different color than the average pokemon of their species, shiny pokemon also have an increased risk of being born with or developing sensory problems. Blindness (or cataracts), deafness, loss of ability to smell, and similar things. It is nearly guaranteed that a shiny pokemon will develop such difficulties about two-thirds of the way through their species' average lifespan. The sense won't always go away entirely, but can dim to a very low point where it is nearly useless. Some species are more likely to dull certain senses than others, but their chances remain the same.
