The cats like flinging themselves across the floor vents and blocking the air and were far too stubborn to move, so I thought maybe there was a compromise. I came across this and figured what the hey, maybe they’ll use it now and then.Oh they used it all right. The second I plopped one cat down on top of it while the heat pump was running, her eyes went wide and next thing I know, she’s deliriously happy. My lap is no longer the prize cozy snoozing spot. Then the other cat discovered it, treaties were broken, battles were fought, territory was gained and lost. So I bought another one over a different heating vent and peace was once again restored.This thing is sturdy, it holds our 15 pound cat easily. I like that I can take the hammock part off and toss it in the wash. Very simple to put together too. 1000/10 according to the cats.
