Tunnel Size 300 mm Tunnel (LxWxH)*: 300mm x 180mm x 150mm 450 mm Tunnel (LxWxH)*: 450mm x 180mm x 150mm * All sizes are approximate Description All of our rigid tunnels are made from excellent quality printed cotton fabric and lined with cosy polar fleece. The main tunnel is made with safe foam keeping the runnel rigid but will collapse if your little explorers decide to try and climb on it. An ideal place for your little ones to explore in or even to snuggle up and sleep. They are also fun items to have when you are just having some play time with your pets. An unique addition to our tunnels is that of an absorbent mat that sits in the base of the tunnel. Like our liners, pee pads etc these mats contain Zorb™ Silvadur® inside which is highly absorbent and antimicrobial. Perfect for soaking up the inevitable wees and locking the moisture and smells away. Supplied slightly larger to allow for shrinkage. These tunnels are rigid and keep their shape and have entrances both ends so your furry friends won't feel trapped in them, so ideal for them to get away if there is a little disagreement in the cage. Your colour choices define the outside fabric pattern and the inner fleece colour. The underneath may be a different colour.
