Not as strong, as the  one I bought years ago, for Sam.
my male cat likes to claw the rug cover, there was a staple sticking up on the front right  side of it !!
I pushed it down with a hammer and put some duct tape on it !!
Smokey has the carpet clawed to pieces on the old one.
I have to have two, because Maria sleeps on the old one.
It serves the purpose I wanted it for.
