These things drive me nuts. I don’t know if I just have less patience than I used to, or whether my mind doesn’t slip into abstract mode like it needs to, but give it a try.
There is an animal in this photo. I’ll even tell you what it is; it’s a cat.
There. Now you know what you’re looking for, and you know roughly how big it will be relative to its surroundings.
Should be easy enough, right?
Hope you have better luck than I did. Don’t spoil it once you find it.
There is a “Click to reveal” feature on the original source of the photo, but that would be cheating, and you’re better than that…
