we saw the reversible snuggle tunnel and thought it would be ideal for our house rabbit to snuggle up in, so we ordered it, but on arrival it did not turn out to be what we expected, on looking at the photo it looks like it is more sleeping bag shape with one end sealed, rather than a tunnel also it was a lot smaller than the photo leads you to believe, they must have used a very small rabbit in the photo. I know sizes were given but we did not actually look at a tape measure and relied on the photo. our rabbit does go through it but it is a tight squeeze. he prefers to throw it around so he is still getting some fun out of it. maybe a suggestion would be to look at the verbal description and maybe a more clearer photo or possibly 2.
