Pets Love It: The pet tunnel is a toy for cats, kittens, rabbits, puppies and small pets to play with. When tried, it is also a cat bed. Safe and Durable: Made of ultra-strong, tear-resistant polyester wrapped around the spring steel frame with protective ends to ensure the cat's safety p> Two Ventilation Holes: The cat tunnel has two ventilation holes, which provide more flexibility for pets to move freely. We can also watch their play inside through the window. Foldable for Easy Storage: The quick-folding steel frame design takes up less space. When not in use, the pet tunnel is also easy to contract and store in the black bag.
