Bests & Worsts Reviews from Amazon

I bought this X Mat to prevent my cat from having accidents on the couch. I opened it and put it on the floor. Immediately, my cat investigated. Within minutes, he was laying on the mat as if it were extremely comfortable. I am totally at a loss of what to do now, except to return this mat and try something else. For what it's worth, I think that heavier animals would be more deterred more than my relatively lightweight cat; the nubs are really quite painful! I rated this 2 stars, because it was not useful for me. NOTE: The shipper was great and the items arrived as expected -- 5 stars for them.
