Cats just want to have fun
I bought this for a kitten that we are fostering. She absolutely adores this, running through the tunnel and sleeping in the cube. She has got 2 of my cats playing with her and they chase each other through the tunnel and going into it themselves. The only reason that I have given 4* instead of 5* is that the velcro connectors aren't big enough and rough play can cause them to come undone. But, they can be done up again.
