There are a million and one reasons to have a cat. They're hilarious, they're soft, they're adorable, they're very pet-able, and they're total badasses who we love to no end. Some people still don't get it though. Somehow, it's lost on them how amazing cats are.
The twitter account "Why you should have a cat" i.e. @ShouldHaveCat has decided to take it upon themselves to become the best resource for explaining why everyone should have a cat. Or, in their words: "The perfect account to show to your parents when you want a cat".
And they do it all without saying a thing. All you need to convince people that they should have cats are cat pictures - out of context and absolutely purrfect.
