how large is the opening

Opening is 6x6. Big cat still can squeeze easy, but the same size dog - don't know. Dogs are not as flexible and squishy:).

The opening for the cat to pass through is 5 1/2 inch by 5 1/2 inch - our cat is small and the opening works very well. The package includes a template for cutting through the wall - it says rough cut opening is 6 1/2 inch (wide) by 7 1/2 inch tall - I think this is about correct.

About 6" x 6" (and that is actual opening, not including the arch). I have a 13 lb cat that fits just fine.

The opening is just under 6 inches tall. Once inside there is about another inch of height because of the molding on the top.

Approx. 3 inches opening. These are nice thick water goblets. I did find them at the DollarTree. They also have great thick wine glasses, too.

The opening is 5 and 3/4" inches or 14 cms. However after I put my fish that I had for over 3 years in it, 5 days later they all died. Two goldfish and one molly. I washed it out and put the same water in from the Aquarium in it and they died . Hope that helps

The opening in 4 inches in diameter. You will have to be the judge on this issue.

to be honest, I have not measured the opening. However, my husband and I have crawled through the tunnel when playing with our son. It accommodates a medium size adult easily. Our son loves to sit inside perpendicular to the opening and roll backwards across the living room. This maybe the best toy we have purchased him in a long time. I highly recommend.

I just measured it. When it is fully expanded the opening is 4 inches wide.

I can't say for sure (because I installed the slot at my mother's house out of state) but I think it's a 7" opening. On the other hand, I recall that the face frame wasn't as wide as the old slot (and so I had to jury-rig the screws on one side to attach it to the door. Buyer beware!

The diameter of the opening is pretty large. Mine is in storage but I'm thinking 1 1/2 inches. It has an Eye Screw in the side that you can screw in and out to adjust accordingly. We were very happy with ours. Hope this helps

The interior opening is about 7"x4.75". I also have a very small child (21 lbs and 32") and she is able to use it with no problems.

Check size, the opening only needs to be larger enough. 2" or larger. Estimated.

I Michelle, I measured about the same - actual opening is slighly less than 6 inches, 7 3/4 inside. This is a great piece. Take care.
