NO MORE COLLAPSING TUNNELS. Now using zip ties to hold those tunnels open. This is made with a 100% cotton print on the outside & your choice color fleece from the Dropbox for the liner & cuffs. There is a single layer of Uhaul pad between the tunnel layers for more absorption. Comes with an OPTIONAL solid matching fleece pee pad Measuring 6x11 & running the length of tunnel. There is a layer of uhual pad between the fleece layers. It’s a great little place for your little ones to hide away or race through. I tested it out on my girl piggies & they went over the tunnel then went through & never came out for awhile. So funny!! Measures approximately 10x11 LAYING FLAT. It can open in height to roughly 6 1/2. I will sew zip ties in place on each opening to keep this open. Please feel free to ask questions. These are handmade items measurements may be just slightly off. Christmas Season Small Animal Tunnel Hideout Playhouse For Guinea Pig/Hedgehog/Ferret/Chinchilla & Other Small Animals
