Petlinks Scratcher's Choice+ Bed Box & Refills features a bed box containing two extra-large stackable catnip-infused reversible corrugate scratch blocks. Large enough for your cat to comfortably rest, you can stack the scratch blocks inside the bed box for a scratch & lounge area. Or use one at a time for a scratcher that cradles your cat as they scratch and rest. Scratching helps cats stretch, tone muscles, promote healthy nail growth, & even helps alleviate stress. Petlinks' stylish innovative cat scratchers offer various combinations of scratch surfaces & angles to please any cat & redirect natural scratching behavior away from furnishings.
