【Fluffy Material】The fluffy texture is very soft to the touch. Made with short-pile flannel fabric and waterproof processing, it's soft and provides excellent heat retention, offering a sense of security that deeply envelops your pet. 【Three-Dimensional Support, Non-Deforming Design】Using high-rebound material, it won't collapse even after long-term use, firmly supporting your pet's body. The internal space is wide and provides good warmth, suitable for all seasons, but especially ideal as a hamster house for autumn and winter. 【3 Sizes Available】We offer three sizes to meet the needs of all small pets. An ideal sleeping or play area for small, medium, and large birds and small animals such as rats, hamsters, squirrels, and hedgehogs. 【Hanging Design for Effective Space Utilization】Can be hung inside the cage with hooks, allowing for flexible layout as a play area or sleeping space for your pet. 【Enveloping Design】The surrounding shape provides high heat retention, allowing your pet to sleep comfortably even in cold seasons. Small holes and a large space simulate a squirrel's tree nest in the wild, matching the instinct of small animals to want to hide somewhere. Provides a comfortable and private place for small animals to rest and sleep. Unused item, opened. Opened to check the contents. Please understand and purchase accordingly. 0205-2
