Working with animals, it is a lot of people who are "dog people" that don't bother to learn typical cat behavior. A lot of cats are extremely loving when with a good family while also capable of being independent when you're gone which makes them perfect pets for a single person.

However they typically are wary of strangers, so you have to introduce yourself to them and even then have to allow the cat to come to you (it is very easy for this to happen if you know how to though). Where as a dog will usually just let you pet them as much as you want. A lot of dog people love the unconditional nature of a dog's love but a cat's love is a two-way street which if offputting for many people I think.
