All Neater Feeders are designed for your pet’s maximum comfort. However, taller dogs in both size classes will appreciate the added comfort of our optional leg extensions, which raise the bowl heights of the Neater Feeder for Small Dogs and Cats to 4¼ inches and the Neater Feeder for Large Dogs to 11 inches. In addition to being more comfortable for your dog, Leg Extensions may improve the performance of your Neater Feeder by containing more of the spills and splashes created by taller dogs. Made from recyclable polypropylene plastic and is top rack dishwasher safe!
