If you're an animal lover like we are, you know the joy of seeing a friend's cat when you visit. While some of them are super friendly with pets are aplenty, it's when you win over that shy kitty that you know you're officially welcome. But there's always that one type of kitty, the one your friends tell you to avoid: the twitchy kitties. These are the kitties who will attack without warning, and it could be because of a medical condition, or that's just who they are, but regardless to say, that's when they get labeled as "evil."

Of course, there are varying degrees of evil when it comes to our feline friends. They could be perfect angels who seem just to know when something is amiss; if you happen to own one of these kitties, you should count your lucky stars. But what about the middle ground? Sure, some kitties are mostly good, with a hint of bad and vice versa. Then there are those kitties who are truly evil, tripping you and pranking you at every turn of a corner. With a glint in their eye, you know they love causing trouble. Many cat aficionados would call this devious behavior catitude, but there are times where we just call it jerky or evil behavior.

Let's take a really hard look at your relationship with your kitty. Are you in perfect sync with one another, or are you constantly at odds? Let's see if you're purrfectly paired or if there is something evil afoot!
