【Product Description】 Introducing the popular "2-Story Kurukuru S" for small animals to combat lack of exercise. This design combines a running wheel with a two-story structure, allowing pets to exercise by going up and down the ramp, encouraging natural behaviors within the cage. It's ideal for the breeding season in early spring when activity levels increase, and recommended for creating an environment where nocturnal hamsters can get sufficient exercise at night. The easy-to-spin and stable running wheel helps alleviate lack of exercise and reduce stress at night.

Its space-saving design allows for installation without cluttering the cage layout. 【Compatible Pets】 ・Hamsters ・Other small rodents *Please check the images for size and installation examples. 【Product Condition】 ・New, unused ・Original box included ・Stored at home (no pets kept / non-smoking) 【Shipping】 ・Carefully packed with waterproofing for shipping ・Anonymous shipping ・Immediate purchase OK 【Recommended Points】 ・For small animals concerned about lack of exercise ・For those who want to increase nighttime activity ・For those who want to enhance the exercise environment within the cage ・Also recommended for those starting pet ownership As this is a popular product, those considering it should purchase soon.
