UODATE: It works! I have high hopes for this to use for my cats to go in and out of their litter box for the sole purpose of catching litter from their paws to decrease tracking. I will report back on if it works. I plan to use a large rubber band to secure it to the litter box opening... being a nurse I love to MacGyver everything to make it work for my needs! Krinkle Collapsible Cat Tunnel with Peek Hole and Storage Bag by Weebo Pets (5234;, Blue)

Great

First, our cat is crazy about tunnels, I mean any tunnel. So, as spoiling parents, we got her several tunnels throughout the years, but also she has different tunnels in different rooms at the house. Besides that the material and the finishing of this particular one is really good, for some reason, it instantly became her favorite. I thought it could be the location, but I tried and switched it with the two other tunnels we have in different rooms, and she simply goes to this one wherever it is placed. If you are wondering, the two other tunnels are the same color, and one of them is practically the same material but from a different manufacturer.

My cats love this tunnel! It keeps them entertained for a long time. The 5234; one is a good size and my very large cat can move through it easily. The middle hole is quite a bit smaller but that doesn't stop her from enjoying it overall. They play pretty rough with it and it appears to be holding up well.

Good size, not too big and not too small! Very durable!

Very satisfied with product, my cat loved it.

My cats cannot get enough of this tune. They chase each other over and through the tunnel. They are sturdy and collapsible to put away easily

Lov

Bought this for my 2 kittens nearly a year ago; now they are almost adults and weight over 10 lbs. each. They still love to jump into this tunnel, run, dive, and pounce. They also like to sit inside while I pull it around, like a sled. I think this was a great toy purchase and will buy another if this ever wears out.

My cats love this. They poke their heads from the center just like in the picture. It is a very good quality material. However, it does not make the foil-y noise that some tubes make which is a little bummer. My kittens push it around with their heads which is really fun. They chase a laser beam which can be seen right through the tube so they run after it thinking that it is inside. This is a very good quality product at a very good price.

My cat and I both love this tunnel, but do know that if your cat is large and/or doesn't like small spaces, this tunnel is not for you. It's small, but it's also flexible, which my cat dearly LOVES. A larger cat might avoid the smaller space. Depends on your cat!

My cat loves it

The rabbits love it. My two old cats seem to as well

I actually bought the tunnel for my rabbit. He digs it.

My cat likes it, and that's enough for me. Quite long, longer than her old one that I had to discard after wear and tear. Sufficiently crinkly for her interest.

Cats love playing in them

My cat Evenstar loves this. Very sturdy, and a good color.

So happy I bought this for my kitten, he loves this

Couldn't ask for a better cat tunnel for this price - love that it's got an internal spring, so it doesn't bunch-up or collapse when our rotund male cat gets a running start and dives into it. Carrying bag is nice and probably very handy if you have to store the tunnel in between uses or your kitty is a seasoned traveler, but ours love theirs so much that the tunnels stay out all the time and never go back in the bag. Boy cat got the blue 3634; one first and loved it, although he is a bit chubby and would probably do a bit better with the 5234; one; our dainty girl cat is perfectly fine in her pink 3634; tunnel. Just based on that, I'd guess the 2034; tunnel is likely only suitable for kittens and very small, slender adult cats. Material wipes clean very nicely, so if you have any puking-from-overexcitement incidents like we have, it should be pretty easy to clean up. If nothing else, it has provided hours of entertainment for us humans, to watch our cats diving headfirst through the length of the tunnel, dropping in Dukes of Hazzard style through the port hole, or seeing a rogue cat ear/paw/eye poking out through the top. Also pretty fun to dangle fishing pole-style cat toys through the top and watching the tunnel shake, rattle, and roll as the cat inside tries to grab it. Only one word of caution: boy cat seems to enjoy laying in wait inside the tunnel, out of clear view, and will jump out at unsuspecting feet as they pass by...a bit startling in the middle of the night, I'll admit...

My cats loved it!!!
