Review on 🐱 K·1 Cat Toy Balls: Interactive 8-in-1 Bed Cave Condos with Tunnel Tube - Portable, Foldable & Scratch Resistant Fun Toy for Indoor Cats by Melissa Dean

I bought this item in 3 colors: pink, new green and blue. Pink is different from the other two colors and does NOT match the other two to connect them. They are not compatible! Green and blue match and connect to form a tunnel from the image and also looks and feels very different than pink. I'm very disappointed with pink (it also works in some places) I love green and blue. They are probably from different manufacturers. But they have to say it because it is not compatible with others. Very disappointed in pink.
