Review on 🐾 Luckitty Cat Woven Sisal Scratching Barrels Tunnel: Glow in The Dark, with Plush Balls and Luminous Collapsible Design - Perfect for Small Pets like Cats, Rabbits, Kittens, Ferrets, and Puppies by Joy Anderson

My cats really like this tunnel - they prefer to stand on the sisal sections so I'm very glad they are wide and strong. Unfortunately they always knock off the smaller side (as seen in the photo) so I have to fix it all the time. Not sure what will solve this problem, if it had supports going down like a traditional tunnel it wouldn't be as easy to store (which is a great feature). Overall I have to give it four stars because while I find it uncomfortable to keep adjusting it, my cats haven't stopped playing with it.
