Plenty of room for my 65lb lab and her 40lb friend.  Cats love it also when the dogs are out playing. Easy to put together. Looking forward to helping my senior dog stay off her floor bed and onto a more cushy bed all winter long.  Only down aspect was the tape used to hold the box together was not very secure and was un tapped upon delivery.  Thankfully all parts were still inside.

My cat really loves these. He watches them bounce around and I leave them in a little box. When he wants to play, he picks them out of the box and drops them, then chases them as the bounce away. Even better, I love to play with them too. My kitten and I will play together. I will throw them and he will go get them. For some reason he likes the blue ones best, but that might just be a fluke. Out of any other toy (and he has many different types), I am buying him a second set of 12. Our dog likes to eat them if he can get a hold of them. Many are probably under the bed too, but I think it's worth it to have more if I find them from underneath.

Both of my cats love to play with this toy. They wear me out playing with this.

My cats love this toy!  It is so simple but they adore it. I'd like to give them extra play it by putting treats in the ball area. They will play around trying to get the tree out for a few minutes. They get mental stimulation along with scratching their claws.

My Cat's love playing with them..what is nice is they are very bouncy too so when u toss them they bounce all over the place.. Our cats love it when we toss these balls on our stairs to the 2nd floor they go nuts now they want to play anytime your by the stairs..

My cats love this toy. They will take turns attacking and pouncing it for quite a while. We only let them play with it for about 1/2 hour at a time, so it doesn't loose its appeal to quickly. Its perfect if you need a distraction (for instance if you are cooking and your kitties get underfoot).

I bought this tunnel for the Friends of Felines Rescue Center.  They take off the zippered ends and use this "fun run" as entertainment inside the center for their rescued kitties.  It is often put down for them to play in overnight.  Since they have a 24 hour web cam on Ustream, the public gets to enjoy watching them play in and on it.  It is one of the favorites among the kitties and the watchers.

It holds up pretty well considering there are up to 80 cats playing on it.  They have as much fun rolling over the top of it as running through it.  After a period of months, it will get destroyed and one of us watchers will get them a new one.

This is a a really fun toy for the cats.  I don't have any experience with using it outside.  As with all cat toys I would inspect it frequently to make sure it is safe for you kitty.

My 4 cats enjoy this quite a bit. At treat time, I put a few treats on each level so they have to work for it.  Inevitably, one or more of them continue to bat the balls around long after the treats are gone.

The cats love it, and since they're such treat junkies it's good to have them get some exercise/stimulation while they binge. :)  the only problem I've had is the dog likes to steal it from the cats for herself!

It's been two months and the fur-kids still love it. I bought extra batteries, but haven't needed them yet, and the cats play with it every day. Occasionally it goes missing, when one cat runs off with his "prize" but it always reappears again.
I put the mouse in a big old drawer from a dresser. This keeps the mouse confined and it runs very well on the smooth wooden surface. When it hits the corner it just turns around. The mouse doesn't work well on my carpeting, which has a longish pile. But the cats love playing with it in the drawer.
It's also a very sturdy toy. I was a little worried at first because my bigger cat is not known for being gentle with toys, but it isn't showing signs of abuse yet. The best part is that it is interactive. It responds to the cats which seems to make it all the more interesting to them.

Ive had this for over a week. Both my cats love it, and play with it non-stop. They also use the scratching part, so its nice to use it as an extra scratching post.

This provides nice entertainment for my three cats.  Every day when I shake the treat container, they come running over to the game.  I sprinkle the treats throughout the board and it takes a good 10-15 minutes for them to fish them out.  The cats are so funny, for some reason they each have their own place at the board, and never deviate from that spot.  It's fun to watch the cats trying to get the treats. This item is very easy to clean as well, I just place it upside down in the top rack of the dishwasher.

Switched out the regular balls for these ones and the cats love the track ball even more than before. Even the chihuahua loves to play with it. Definitely recommend these

The cats love this! Even the dog enjoyed it! I bought this for my cats but it quickly became the favorite toy for my roommates cat and my other roommates dog. Wildly popular and smells great! Will be buying again.

My cats already love to scratch up the good carpet, and this toy just encourages that. Scratching posts make more sense and are different enough looking for the cats to make the distinction.

Its working out great for my two cats.the house is shared with two dogs and this gives them a secure space to see everything.
