Review on 🐱 PetFusion Jumbo Cat Scratcher Lounge, White - 39 x 11 x 14 inch (LWH), 4 Cardboard Scratching Surfaces & 2 Levels - Scratch, Play, Perch, & Hide - 100% Recyclable Cardboard Cat Lounge with 1 Year Warranty by Linda Rodgers

As a roommate to two boxing connoisseurs, I can attest to their opinion that this is a top product. There were no instructions in the kit but it is obvious that you will need to cut a hole on the side. The box is strong enough to accept this modification without compromising structural integrity. A big plus, this product is modular and connects to boxes from other manufacturers, see photos. The packaging was odd as the box wasn't secure at all, but it came with a very large, strong packing material that held its shape well. from inside.
