All perches are curved so your cats won't fall off while sleeping. All openings are large, and enclosed areas have at least two escape routes. The hardware used to attach components is solid and strong. Components won't work loose over time. We use thicker, more durable forms.
Many companies depend on their products to wear out in order to get repeat business.
In contrast, we depend on our products to last. And they do. We get a lot of referral business because of the quality and lifespan of our trees. A less expensive, and lower quality tree will often have to be replaced in a year or two. A top-quality Angelical Cat Company tree will last five to ten years, and very often longer.
