I like to imagine that this is asking if you're a cat or dog person, so I'm going to say cats, as I've had them my entire life. While I do like dogs, I wouldn't want one for myself because they're noisier than cats, and you have to take them out so they can piss and shit (whereas with cats, you can teach them to use the toilet in your bathroom if you don't want to deal with litter boxes).
I should mention I'm currently volunteering at an animal shelter called P.A.W.S. If anyone would like to donate money to it, here's the link: PawsTinleyPark.org/ways-to-donate/
