For years we've been hearing about little bun buns lounge on REAL grass. That's why we've created a grass potty box just bunnies! Give your furry friend the hop-portuity to have their own backyard in a box with BunnyLawn. Just pop open the box and let your bunny get back in touch with Mother Nature with a lush, grassy pad of their own to loll around on. Details 12 x 9 inches. Hydroponically grown outdoors at a sunny sod farm in California. Keep it indoors (or out) and mist occasionally to keep the grass thriving. Perfect for hamsters, guinea pigs, hamsters and hedgehogs too!
