My 7 week old kitten is loving this tunnel. She has a smaller single tube she was seeming to get really bored with, so we wanted to try this multi-tube and it was been a huge hit. The tube crinkles (like a baby toy/book) which is a fun bonus for my kitten. She enjoys playing peek a boo with us in this tunnel. There are two drop down toys at the end of each tunnel and the center has a hole so our kitten can peek out. This would be great for other smaller animals as well, not just kittens!
