The 'Cats that Look like Pin-Up Girls' Tumblr features a variety of similarly posed felines. Once the pinnacle of female sexuality, pin-up girls have changed and evolved throughout the years to become the modern day Playboy Bunnies and Sports Illustrated models they are now recognized as.

Paddington the Shar Pei dog and his best friend cat named Butler are perhaps the cutest pair you've ever seen. The two of them live with their owner Annie Jacob and three other cats in Tasmania on the south coast of Australia and are pretty much inseparable.

Internet is filled to the brim with cat pictures and cat videos. It seems that cats became the symbol of the internet. For some unknown reason, cat owners simply love taking pictures of their beloved kitty-cats and posting them on the internet for all to see. Everyone’s cat is special; however, some are more special than others. Take Garfi for example. As soon as you catch his menacing stare, you immediately realize the reason why this kitty became popular. The look he gives you would send shivers down anybody’s spine. Yeah, the look Garfi has is somewhat special, but nothing will compare to the “facial expression” of Tard – the Grumpy Cat! A look that screams – “All is lost! Life has no meaning…”.
