The versatile RYPetmia Indoor & Outdoor Heavy Duty Dog & Cat Exercise Pen serves as a kennel, crate, hangout spot, playroom, or even a designated time-out zone for your furry friend. It’s suitable for single pals or a big party and can be used indoors or outdoors. When used indoors, you’ll appreciate the rubber gasket that prevents slipping and protects your floors. Made with rust-resistant coated metal and 0.8-millimeter thickness, this durable fence is built to last. The step door is a comfortable walk-through that won’t hurt your furry friend, and the upgraded locks prevent escapes. Plus, this pen isn’t just for kitties or pups, it’s also useful if your pas is a rabbit, duck, turtle, or guinea pig.
