I used to be a dog person before I meet my cats. I still like dogs very much but kitties are my favorite now, definitely
Before I know cats, I was like you, I thought they were agressive and scraching people for no reason (I was a kid then) and I had some examples from strays that come to see you for food and go back in nature.
I was completely wrong of course.

Adopting adult kitties has another advantage: you can better choose (although the cat will choose you too ) based on the character. Young kitties can change while growing.
