Comfort and warmth for pets: The self warming cat bed features a donut shaped exterior made from ultra soft plush to keep pets warm and cozy in cold weather. Raised edges offer a sense of security and convenient head and neck support, while the soft padding can help relieve joint and muscle discomfort and reduce anxiety. Suitable for indoor cats and small dogs. Easy to clean and durable: The pet bed has a non slip bottom to keep it in place. It is crafted from materials and workmanship and is machine washable. The bed undergoes strict quality inspection to ensure reliability. If you have questions, customer support can be reached by email with a response within 24 hours. Packaging and setup notes: The pet bed is vacuum packed and compressed for long storage. When first opened, it may appear flat. Shake or tap the bed and allow it to sit for 12 days to regain fluff. The sponge cover expands fully upright after unpacking. Rebound of the compressed sponge cover may take up to two weeks. As shown in the product photos, allow full recovery for feel.
