If you own a dog, your dog could be carrying an allergen that could reduce the risk of going blind through glaucoma. However if you own a cat, your cat could be carrying an allergen that actually increases your risk of going blind through glaucoma.
Apparently cats are not only trying to rule their human servants, but they’re making sure we can’t escape from them as well. If you thought your cat was secretly plotting against you, you could be right. Perhaps your cat is even behind the conspiracy to invade Texas, cover up the existence of flying saucers in Area 51, and hiding the real killer of John F. Kennedy.
