Why do cats want to be with the person who is allergic? Many cats seem to gravitate toward people who are allergic to cats, or don’t like cats. This isn’t because of malice; it stems from cat body language. When cats greet each other, it’s considered polite to look away. Or, they look at each other and blink slowly. To a cat, this means, “I trust you so much that I don’t have to see you.” In the same way, people who try to avoid the cat and won’t even look at it can be interpreted as safe. There’s no threat, no pressure to perform or do anything, and the allergic person’s lap can come across as a safe and comfortable place to rest.
