Not suitable for "wild" cats
The product is good by itself, but is not recommended for cats that usually use their claws.
My cat always run and play and slide while running etc etc... his claws made some holes in the carpet letting the cooling liquid inside come out... and i think that it could be poisoning if the cat licks it...
Maybe this carpet should have some more protection, or more resistant surface, when is given to a "wild" cat :)
