When others complain, from time to time, about not seeing a particular image here at the asterisk, I can always see it. But this time I'm the one who can't see it.
The link is to [that site]/cat-peeking.jpg. But when I click the link I just get the site's base URL, not the image URL, which indicates they're redirecting. That's common on blog sites because they want people to land on their current page.
Scrolling down to the bottom of their landing page I found a link to the archive of June posts. Clicking that and scrolling down I got to a post called "IT'S CATURDAY! 20 Funny Cat Photos". Clicking that I got to the 20 cat images, and finally scrolling down I found a few images which included both a cat and a boy -- but none which to me made sense as regards your question about a boy or a cat looking out a window.
Incidentally, in the top post you say "Please also try this explicit link", but all three links -- the image I can't see, the "Click to view full size image" link, and your explicit link -- are all exactly the same URL.
I suspect that you and a few others saw that image and it is now in your browser's cache. I didn't get to it before the site had refreshed its content, and therefore it's not in my cache.
