I hate cats, and they still like me. Seriously. All animals seem to like me, for some reason or another - its the animal magnetism.
In all seriousness, cats are as worthwhile as having a high maintenance wife who uses you only for you to buy her stuff and pay for her credit cards. Otherwise, she does her own thing and uses intimacy as a bargaining chip.
Dogs are like a fun friend who always want to hang out and are up for whatever you are. You don't need to give them anything except attention and the occasional scrap from the table. They expect nothing but will give everything.
I own two siberian Huskies that are sisters and a Doberman boy. My girls love to play and relax and my boy is always at my side. I trust him with my home when I'm not there and to protect what is mine if I can't. I could not ever do the same with a cat - whether a domestic or lion.
