No clue how to explain this one, so your best bet is to just create your own backstory. I'm debating between two scenarios:

1) It's the office party for Harry's Auto Repair (Harry's pictured in the middle)


2) That this cat is actually a realtor and he just sold this house to these people. And that this is the picture the cat's putting on its Cat Realty website with a caption like "Another Happy Home!" 

Both of those HAVE to be more likely than someone randomly taking a picture and the cat just deciding to pose for the shot. That doesn't happen. No sir.
