My senior cat was having trouble getting up and down his cat tree, but I couldnt find a new one that had all the elements he loved. This was the perfect solution! I placed it right beside the old tree and now he can use it like steps. It wobbles a bit, which worried me at first, but its just flexible, the spring-loaded top keeps it secure. I never worry about it falling over even with his 12 pounds and a kitten leaping up and down it. The steps can be at any angle, which is great for a small space. It does need to be tightened periodically as it settled or cats move it around, otherwise the wobble gets more pronounced.
