Positive. My cats are attracted to the material. They revert to a more tranquil mood.
It took my cat a couple of days until he realized that he can go inside instead of just laying on top of it. Now it’s his favorite nap/hiding spot! Love this product!!
I bought both sizes since one of my cats is bigger than the other. The small is definitely for a small cat! Neither one of my cats will actually get inside, but one at least likes to play with and on them. They're great quality and look good, too.
