Make potty training easier for you and your pet. This 100-pack pet training pad takes away the hassle of litter box maintenance. A litter box that won't stink up after several uses will encourage your pet's continued use. These ultra-absorbent 18" x 13" pet rabbit toilet training pads are a perfect fit with litter boxes like that of the 17.3" x 13.4" x 7.1" CalPalmy Large Rabbit Litter Box. Perfect for toilet training rabbits and bunnies, guinea pigs, ferrets, hamsters, rats, and other small pets. You can use these pads as-is or as an absorbent lining on the bottom tray of the litter box. No tracking, no leaks, these pads may look thin but it can hold up to 3 cups of liquid. In comparison, a large, 11-pound rabbit can urinate as much as 2.7 cups for an entire day. Guinea pigs, on the other hand, can drink up to 20 percent of their weight. This usually amounts to 0.42 to 0.84 cups of water. A hundred pads would surely go a long way especially that you'll only need to change it once a day. Take note, these pet toilet training pads are only for small pets like rabbits and guinea pigs. The pads can indeed hold the amount of urine produced by cats and puppies but the pad's surface area may be too small for these animals. Also, these pads aren't suitable for animals that urinate a considerable amount in one go. They work well for rabbits and guinea pigs since these pets only urinate in small quantities, several times a day. Double-check the dimensions of the pads and their compatible CalPalmy Large Rabbit Litter Box. If your pet won't fit in the CalPalmy Large Rabbit Litter Box, your pet may not be also fit to use these CalPalmy Pet Toilet Training Pads.
