You’ll need a Pokeball to catching a Pokemon. How about Cats? It’s even easier! Using a “square”, then the cats will go into it with not doubts!
It’s so simple, you only need to prepare a roll of adhesive tape, and then make a square (the blue square above), then sit down and prepare your phone, and you can see that the cat enters and stays!

The scientists mention that, the “square” can make the cat feel so safe, this is why they would love to stay inside the square.

Well, it doesn’t only works for cats. Using a square, you can also keep a dog within it. Same logic, easy and cheap, just buy a roll of adhesive paper!
