DOG LITTER or SHARP BARK PIECES are uncomfortable on paws. When purchasing a litter box, IT IS IMPORTANT TO PURCHASE A LITTER BOX THAT HAS SIDES and a low entrance for easy access. Sides on the box act as a splash guard to keep the mess in the box, UNLIKE FLAT TRAY UNITS which permit urine to be sprayed everywhere. The realistic anti-microbial grass has mutiple perforations in the rubber backing allowing urine to pass through to the basin below. The GRASS IS MACHINE WASHABLE in cold water. The grid locks in place so your pet feels secure while in the litter box. Complete washing machine instructions included. Grass will not stain. Your order comes with training tips. The grass has a NATURAL SCENT to attract your little one to using the "Little Squirt", BUT UNDERSTAND THAT YOU MAY HAVE TO TRAIN YOUR DOG OR PUPPY TO THE PRODUCT AS WITH ANY HOUSEBREAKING METHOD. If you have any training questions, all e-mails are answered the same business day. Unit also can be used without the grass. The holes are small enough in the grate to form a surface that is gentle on your dog's paw pads. PLEASE, NO SHIPPING TO A P.O. BOX or to CANADA.REFUND POLICY: Customer responsible for shipping the COMPLETE unit and grass back to the office. The unit must be unused to return in the original packing box within 10 days.
