Now, it's fairly clear that the people who made this study have never owned or interacted with a cat.
How do I know this? Because their advice to minimize developing a cat allergy is to wash your cat once a week.
Trust me on this one - don't ever, ever try to wash your cat. There will be blood. You will end up in a battle you will lose. Plus, do you really want your family to know that you were murdered by a small pet?
