Cats are a great conversation topic. Owners can go on for hours about the oddities of their endeared furry ones and lovers can go on end about their utter cuteness. So if you are trying to pick someone up with a cat line, you might want to double down with follow-up kitty conversation.
So what are good topics? Well, you'll want to know what race it. Many actually don't know, "it's ehm... a cat!" It's easy to bust their balls on this to create attraction. You'll also want to know its name. There's always a story behind it that people love to tell. Fluffy, Mr. Dimples or whatever name they say, use this as an opportunity for a little flirty teasing. If the name is just a little weird, I like to say something like: "Yea, if we ever have kids, I got first dibs on the naming". Boom! Attraction initated.
