How many cats did you see?

At first glance, it looks easy… but this image hides several small details that many people don’t immediately notice!

Some people see 9 cats, others find 10, 11, or even more by carefully observing the tiny kittens hidden in the picture.  This visual challenge tests: your observation skills,your concentration,

 and your ability to spot details invisible at first glance.

 Look at each group of cats slowly… some are hiding behind the larger ones!  So, how many cats did you find? Be honest!
