YOU could have the eyes of a hawk if you can spot all four cats hiding in this optical illusion, but it’s stumping viewers.

The photo features three tiny black kittens sitting on gravel and mulch, but there’s a fourth feline in the bunch.

It can be seen blending into the dirt and mulch in the upper left corner of the photo.

The photo, shared on Reddit forum Confusing Perspectives, reads: “Hint – the fourth one isn’t the same colour as the other cats.”

One user claimed: “I see five cats!”

Another said: “Catmoflauge!”

One girl replied: “Wow! That really was a challenge!”

Answer: I’ve been looking for 10 minutes and still can’t see the 4th
