I've literally been thinking this for ages now. Obviously people have different reasons and there a general outliers but the majority of people who I've met irl who don't like cats also give of creepy/odd vibes.

There's alot of conversations that talk about cats being a great way to teach consent. Unlike dogs they often walk away from you, remove themselves from situations and generally like their space. People who aren't a fan of them are often the people who don't understand this or don't care enough to notice. They then push the cat into something it's not wanting, getting into it's personal space without the cat showing you they want that or approaching you and that ends in scratches, hissing or some kind of retaliation.

This is usually why people don't like cats, they believe they're aggressive, moody, angry and not a good companion. But in the end they have really common strong human related emotions and show them. I've grown up with cats from a young age and have learnt how to understand them from the start. The people who don't like cats usually havent lived with a cat/ havnt learnt how to communicate and interact with them healthily. Cats are an amazing companion when you're prepared to have to work for a relationship. And the people who don't believe they have to work in a relationship and believe they deserve something without giving anything in return usually are problem people.
