When you watch this cat playing fetch, everything seems normal until you realize that you're actually watching a blind cat.
So how can this cat play fetch without being able to see? Cats are equipped with keen senses of smell and hearing. Since the toy is a crinkly toy which makes noise, this blind cat can quickly identify where the toy falls, much in the same way that he would hunt prey in the wild.
In truth, cats are well suited to be able to adapt to blindness. They are highly sensitive and can use their sense of smell and hearing to help determine what is around them. Cats are also equipped with whiskers, which can pick up on changes in air movement and essentially guide the cat around his surroundings. Because of this, cats can live quite comfortably even when they're blind.
If you're thinking of adopting a cat who is blind, then talk with the shelter about what accommodations you can make to help the cat adjust. You'll want to provide your cat with a safe space where he feels secure, and if you have other pets, then you'll need to make introductions safely and gradually. With a bit of time, blind cats can often get along just fine in your home.
