If there's one thing you see more of on the internet than boobs, it's cats.

So innovative Japanese photographer Yuki Aoyama has done what now seems so obvious: combined the two.

His collection, released in a book titled 'Painyan' (a pun in Japanese on the words for 'breast' and 'meow'), contains 96 pages of beautiful women with cute kitties.

The contented cats can be seen pawing at cleavages, settling inside blouses and even resting between two sets of breasts.

Aoyama's book, which was released on May 31, costs about £10 - and is said to offer a therapeutic experience.

It follows previous attention-grabbing work by the cheeky snapper, who released a collection titled 'Schoolgirl Complex' packed full of uniformed girls photographed from the perspective of a teen boy.
