Just wanted to thank you so much for the ramp tunnel idea! Unfortuntely I am in Australia and when I checked the site you suggested they were not doing any custom orders at the time let alone international ones. I could not find such tunnels in Australia. However, after showing my local fleece cuddle cup maker your photo, she was able to make 2 tunnels for me (always need spare fleece items for washing day) which just arrived yesterday. I immediately installed one.
My young lad Peanut Butter, who never had any problems going up the ramp, took to the tunnel right away and proceeded to run up & down in exuberation. The adult boy Hazelnut is the one I really got the tunnel for. He would never negotiate the ramp unless you put him on it, even though I went to a lot of trouble to build sides for the ramp to make it tunnel-like, as he loves tunnels. Well, yesterday he was using the new fleece ramp tunnel but only to hide in halfway up, so progress was made. This morning I just about fell out of my chair as I glanced over and noticed Hazelnut was lounging about in the upper level! And when I praised him he nonchalantly went down the ramp tunnel to the bottom level!
So, I just had to pop this thank you off to you.
