This corrugated cardboard sisal ball cat scratching post combines scratching, play, and resting in one, making it a multi-functional toy for cats to unleash their natural instincts. The main body is made of high-density corrugated cardboard, with a tight, scratch-resistant texture that doesn't shed lint, providing a comfortable grip for cats and effectively protecting sofas and curtains from scratches. The top is inlaid with natural sisal balls; the coarse fibers are wear-resistant and meet the scratching needs of cats at different angles. The ball's shape can also be rotated, instantly stimulating the hunting instinct and keeping cats entertained. The innovative herringbone R-shaped curve design conforms to the cat's outstretched body posture, allowing for more enjoyable scratching with a hunched back. The smoothed edges prevent scratching your pet. The stable base ensures it won't tip over, even with a large cat's powerful pounce. The replaceable corrugated cardboard core is environmentally friendly and economical, while the sisal balls are chew-resistant and durable. It serves as both a scratching post and a cozy little bed, allowing cats to rest when tired. Multi-functional and space-saving, it's a great helper for harmonious coexistence between humans and pets.
