Trying to determine the size/diameter of the largest hole. I have adult cats but they are on the smaller side (under 10 lbs).

I would say that only kittens or very petite cats would comfortably fit inside the base. It's really very small and the openings are very tiny. However cats of all sizes would enjoy sticking their arms in the openings to bat around toys that are placed inside the base. The scratching post with attached ball would work for cats of all sizes.

This is really made for kittens. Now that my cats are over a year old they are to big to fit in the holes and just use it for a scratching post.

I have a large Chihuahua, stands about 15 inches tall (minimum) and about 10 lbs, that could get in, turn herself around, and get back out. Has to do a bit of a shimmy to get out, but a cat her size should have no problem!

There is a "door type" of opening on the bottom that is about 5 inches in width at the bottom. The largest circular openings are about 4 to 4 and a half inches in diameter. My cat is an 8 pounder. She actually has never gone inside of the tree, but it has been the absolutely best scratching post we could find. Don't know if the failure to go inside is due to size or not. She does not in general go hiding at all - so it may be a temperament issue, but dont really know

The smallest of cats. My cat is a full-grown adult but is very diminutive, about the size of an adolescent. My cat's neck is approximately 8.5", and this collar was the appropriate size. Also, I definitely recommend you check out the Neck Hug by Wagtail Farms. That was the best product I found. Hope this helps!

The blue part - which is the green part in the photo - is about 10.5 inches in diameter. The black part is a bit smaller and you can use the string to adjust tightness. They fit my 10 pound female cat just fine.

My cat is ~9lbs and the small was too big but the x-small was perfect although with some effort, she could scratch around it. The opening for the x-small is ~10in and for the small~12 in. Hope that helps.

Hi, I respectfully disagree that this particular model is large enough for an 18 lb. cat. I mentioned in my review that I had a previous (much larger) tunnel and when I ordered this one I didn't think about the diameter of it. My 12 pound kitty wants so badly to play in it but is just too big. I would go up to a larger size (depending on the size of your cat). Hope this helps. Good luck!

I think it would still work. Perhaps you could cut the hole higher so that he would have extra space. Cats are quite flexible!! This has worked great for us! The dogs are sad they don't get cat food anymore!!

Hello. I've been using this on my ~11 pound cat since late September. It took a little getting used to for him, but it's very second nature for him now. I wouldn't say it is 'small,' but my vet verified that it's not too big for a cat his size. You just have to purchase a small dog collar for it so that it is sturdy enough to hold the device upright. Please see the review I posted for this product.

Well, my largest cat is 8 lbs and fits. It is 17" in diameter. I would try to measure cat when curled up asleep. The base isn't real cushiony. Just a heating pad covered with fabric. The ring is soft foam. I'd bet your cat would figure out a way to make it work even if he/she hangs over a bit. I would try it and if it doesn't work, give it to a friend with a smaller cat. The larger beds on amazon are an option but they are double or more the price.

The middle perch is very small. We have a 3 pound kitten and it is big enough for her, but not our adult cat. Our adult cat is 9 pounds.

the small might work but a 10lb cat has a smaller ribcage than a dog of this weight

I have a very small cat who couldn't fit into it... I found it incredibly small for any size cat to fit, except a kitten. I returned it. I wish it was bigger because it was really cute.

My opinion is if you move the archway up it will show more of the bottom of the door. We have a 11 pound cat that goes through the hole with little effort! Just remove the brush and your cat will fit just fine!

Smaller than expected, probably like 10-12 in in diameter. My 12 lb cats fit comfortably. Definately a good deal compared to what pet stores have at their high prices! Totally worth it. Assembly too about 10 min.

Maybe the 8lb cat but not the 16lb one. My cat is 5 and this is his first house that we know of. In order for him to use the hole we had to put treats in it otherwise he could care less about it. He usually jumps to the 2nd and 3rd level. Thr third he barely fits on and he's about 10lbs give or take.

I have a small cat but it can accommodate a medium size one as well. If you have a feline that is larger it wouldn't be a tight fit. I had hoped to see a larger and deeper model sold but no luck yet.

I did not find it too small at all. In fact it seems larger to me than regular boxes. And the sides worked well. My cat is on the small side, though, at 7 lbs.

It can be made into a circle that is 2 1/2 feet long and 2 ft. wide or into a long length that is 3 ft. long. I found that the holes are more for kittens than mature cats. Mine want me to hit the ball while they watch.
