The product can be made longer. As for the balance, if you apply the bottom base in double layers, the weight increases on the base and the product remains stable. Unfortunately, these sizes are insufficient for cats older than 4-5 months. Unfortunately, they can only file their nails on their front paws by bending them. The main purpose of these boards is to provide climbing, they need to use their back paws as well. Our cat is very docile. Even though it is a cat, the classic scratching boards of this size were not enough to file, so he satisfies this need by climbing on our huge carpet that is rolled up and extends to the ceiling, but I would like to find a company that produces a longer scratching board suitable for him. Frankly, even if it is not that long, it is at least a more regular size range where he can climb using his back legs. .
