Living World Lock & Crock Dish for small pets offers many great advantages. Made of extra-thick, chew-resistant plastic, the heavy-duty dish is durable, easy to clean and dishwasher safe. The crock-style dish can easily be attached in an elevated location to any cage wire size and fits vertical or horizontal cage wiring. This is an excellent space-saving alternative to freestanding dishes. Once installed, it will not twist, turn, or tip, eliminating messy food or water spills. The dish can easily be detached for filling or cleaning, simply by sliding the locking device and lifting up the dish. The dish is also suitable for birds.
