The Answer is =>>>    The fourth cat is cleverly camouflaged in the image. If you closely observe the background, near the top-left corner of the image, you will notice the fourth cat blending in with the dark shadows and the surroundings. It’s almost hidden, as its body matches the color of the ground, making it tricky to spot at first glance.

So, in total, you have four cats in the picture, though one is not as easily visible!
