I no longer use the tubing. One of my pigs got his nail caught on something and got it torn off, I think this ramp may have caused it. I got it at Home depot, but I wouldn't recommend it.
I personally use that kind of tube on top of a wooden ramp and my pigs love it. I have been using it for roughly 8 months and even the baby piggies a few days old play in the ramps. I secure mine by sticking it over top the ramp, and poking a hole in the top side of the tube and using cable ties.I got my tube from Lowes. 3bucks for a huge section. I used the remainder pieces for little tube hideys. It makes the coolest sound when they go thru it. You'll be downstairs or somewhere in your house and say, Ohh there goes Little Poopy Pete up stairs..>LOL.... I also have a rescue friend who uses it at her resuce with no problems. I think everyone has had good experiences with it, Your the first person who had a problem. I hope the piggy with the tore nail gets better.
