In my opinion dogs are a lot better than cats. Let me explain why: 

 Cats may be slightly more clever than dogs and be able to jump higher, but think about it, what would you rather have as a pet, something that stays in the house when you want it to and is always happy to play (a dog) , or, a pet that you barley ever see and that will hiss and even scratch you if it's not in the mood (a cat) !

 Of course there is a downside to dogs and that's that you need to take them for walks about 3 times a day. I personnaly enjoy it however some people are just to lazy to get up on a morning.

 Well, there's my opinion please leave your opinion in the comments!
