PUT your vision and patience to the test with this frustrating brain teaser. Everyone can see the dog in this puzzle but only cat-lovers and those with a good eye for detail will be able to spot the cat. Roscoe the cat has been called a "master lurker" by his owners who shared this image on Facebook.

If you can find him in just 10 seconds, not only do you have good eyesight but you may also have a high IQ. The sitting room of the house is tidy but with lots of homely items dotted around, your eyes can easily lose their focus. As well as distractions such as the display case against the wall, the more you start looking, the more spaces you can see where a cat may hide.

For many viewers, the only hint that there is a cat in the house is the toy on the far right side of the image. If you are struggling, know that you are not alone. "I see a dog that matches the chair," one puzzler said in the comments to the image before asking for numerous clues.

For those who feel the same, one hint is that Roscoe is a black-and-white cat. However, he is incredibly talented at blending into his home while being in plain sight so this may not help. Perhaps dividing the image into smaller sections will help you spot him.

In typical cartoonish fashion, Roscoe and Bruce the dog are keeping their distance from one another though the cat has his eyes on the pooch. For those who are still struggling, focus on the room at the back - perhaps the blue clock will give away the answer. If you think you've.
