There’s likewise another variation that’s a tiny longer, yet has the very same answer.

Are you ready to read the answer?
Here’s the Answer
There are 4 cats total.
Why is that the case?
Because we’re talking about a square room, you need to think that this indigenous the philosophy of a cat stand in a corner of the room, v his earlier to the corner and also his eyes dealing with the facility of the room. Native his perspective, the 3 cats in the other corners are all “in prior of him.” and also of course, in ~ the tail of each cat is the cat who owns that tail!
If the cat were standing in the corner with his face against the wall, then it would appear from his view that among the cats was “next” to him fairly than “in prior of” him, top you come think there can be a more facility answer to having actually three cat in front of every cat. But the just logical method to think about the riddle is to snapshot each cat in the corner with his ago to the corner, encountering inward come the room, fairly than trying to smoosh his face against the wall. From the angle, every the various other cats in the room like they’re in former of him.
In fact, this is the only means to have actually a an easy answer. If friend tried to look at it indigenous the view of a cat whose face was against one the the walls, then he might think one of the 3 cats to be to the side of him, rather than in former of him. So climate you’d require to include another cat to the room because that each cat. However this would all go out the window if the cat climate shifted and had his back to the corner.

There’s an amazing discussion around this riddle top top Quora. One responder suggested that there’s no good answer. Aaron Arthurs wrote, in part: “The total number of cats in this square room will certainly be in the variety of 4 to infinity. Let’s break this riddle down… an important but missing piece of information is which means each cat from each edge is facing. If the four cats are all dealing with each various other … there space still four cats in total… but if any type of one of the 4 cats turns and also faces their particular corner, then there will certainly be infinite cats (and boundless mischief). This is to accomplish the problem that every cat faces three cats. It is a result of recursion there is no a end condition.”
A similarly worded riddle likewise gives us the same answer. That reads: “How many cats are in a little room if in every of the 4 corners a cat is sitting, and opposite every cat over there sit 3 cats, and at every cat’s tail another is sitting?” because that this riddle, the answer is the same due to the fact that we’re talking about a little room. The cats space so close with each other that each cat’s tail is bumping into another cat in a corner.
