I started Natural Climbers at the beginning of 2018. My two Sphynx kittens Mal and Tan were one year old and starting to get fat . None of their toys or furniture provided enough exercise. Even the largest cat furniture at the pet store did not offer an engaging experience. A cat does not get any exercise walking up a series of platforms. They need to climb. I began looking for materials that would provide a good climbing surface for cats. I eventual found the Sisal and Coir carpet used in the current line of products. I look forward to expanding the Natural Climbers line of products and offering the highest quality cat furniture that you can buy.
