Love it! I have a 7-9 year old cat. She's a little weird about her toys. She pretty much only likes catnip filled kickers/mice but I wanted to get her something different.
She usually loves sleeping on a specific corner of the bed by the window, or on my legs, but now she sleep on this mat.

Pros:
I can get up to go to the bathroom after waking up if I need to, I don't have to worry that a cat is very comfortably asleep on my legs.
Since I put this mat in her usual sleeping corner, we no longer have a pool of fur on our bed, the fur is now on the mat! (Which is very easy to wash! I just throw it in with our color clothes and leave it on the counter to dry)

She loves the little pocket filled with catnip, the crinkly sound, the feather on the corner, and she loves the little yellow stuffed toy in tbe middle and often uses it as a little pillow.
I have noticed that it also absorbs her body heat pretty well due to whatever the crinkly stuff is.

If you have an older or more chill cat, get this!
I can definitely see this being a hit with playful kittens, too. But for the pickier grumps it works great. It's very comfortable for napping (by the looks of it) and also loads of fun for whenever they do want to play.

Our cat loves this mat. She's not on the furniture as much because she loves relaxing and napping on the mat. It'd be really great if it was about 4" larger since our cat is a bit...large!

My cat doesn't seem to LOVE this but then again it doesn't seem like he loves any of the toys we buy, his go-to toys are ear plugs, hair bands, styrofoam peanuts, and shipping boxes with holes in them. But he does play with it sometimes! It crackles really loudly and I like how it's collapsible, which makes it really easy to transport. There is a hole at the top of the tube where your cat can poke its head out so that's fun too.

One time I decided to be stupid and put it over my head and wear it around my neck with my face poking out of the tube hole and it seemed to scare the crap out of my cat, so....don't do that.

My mom has a few cats.. they don't like to play. They don't like string things, or feathers, or even Lazer lights... I didn't have high hopes for this, but even her play-less cats love this thing. Her cats are more the type to lay in their spot all day...sometimes they will go inside of a box, but it's rare. Anyway, we got this and all 3 of them like to go in it. I think they like it because it makes like a foil-crunching type sound when they go through it.
They might not enjoy any other toys they have, but they sure do get a kick out of this. And mom is all too happy to see them rolling around in this!

The product itself... its fairly inexpensive for a cat toy, so I doubt it will last years, but overall I would recommend it. Shipping was fast and the cats are a little less bored now

My kitties love the tunnel. I connected some cat tents with the chute and they run through and play. Got a couple of still shots. I moved to a smaller place, so put the two tunnels behind the couch. Helps catch cat hair and I can hear the crackles when the kitties walk behind the couch. My brown and white kitty likes to sleep in it.

Packaged and shipped on time. Very happy with the purchase. Much less expensive than the pet stores!
