This portable indoor/outdoor toilet works for dogs, cats, and other small pets. Ideal for apartments, during potty training, and for occasions when you can’t let your pet out, the Pet Loo is a convenient alternative to pee pads and midnight bathroom breaks. The top layer of synthetic grass allows urine to drain through into the base. The reinforced base is slightly angled so urine trickles down into the waste container. The waste container catches the urine and is removable for easy cleanup. The waste container holds 2 liters of liquid and is made of a material that reduces odor. For even easier cleanup, place a Pee Pod into the waste container. These disposable pods are lined with our Wee Sponge powder that solidifies into a gel when it comes in contact with liquid, effectively trapping urine and odors. Available in 3 sizes...Choose a size based on your pet’s size or the size of the location where you will place the Pet Loo. The Small size is perfect for smaller spaces such as RVs, campers, offices, and patios. For dogs who prefer to circle before doing their business, a slightly larger Pet Loo would be better. Small size is 7x21 inches(1.4x1.75 feet/53x45cm) and is perfect for small dogs, cats, guinea pigs, rabbits, or ferrets.
