For young renters with cats, drilling holes in walls often means losing their security deposit. A brand has recently launched a drill‑free version of its solid wood wall‑mounted cat climbing system, using industrial‑grade adhesive stickers and a tension pole for dual reinforcement, while still supporting up to 50 kg. In real‑world tests, three cats with a combined weight of 15 kg jumped on the perches simultaneously without any movement. The product also comes with wall repair paste, allowing renters to quickly restore the wall before moving out. Within one week of launch, 3,000 units were sold, 90% of them to renters in first‑tier cities.
