Smaller
I've been using this set for years in the garden during summer. I use two of them and replace them every other year, because after two summers they do wear out, and the cats also destroy them. They have a great time with them. However, I was surprised to see that not only has the material changed, but also the length of the tunnel is now a bit shorter. The old one measures 94.5 cm from one opening to the other, and the new one is 87 cm. The house is 1 cm narrower, which isn't too bad.
