Cats will always have a special place in my heart. I like their quieter, more laid back form of affection. They're really nice to pet. Relationships with them feel a little more like relationships with people, They won't just instantly adore you and do whatever you say, but if you develop a bond they do care about you in a way that feels special. I also think their problem behaviors are also typically less of an issue than dogs', but I know that's subjective.
