Can you ever have too much of a good thing? Well, it appears you can as some pet owners didn’t realise they were getting two separate tunnels when buying our original and unique Duo Tunnels. So we’ve simplified things and now offer them as a single tunnel. They are still made without any glue or wire and can be safely chewed, get wet and will last longer than their cardboard equivalents. ‘Naturals’ branded and ideal for play and sleep.
