I installed the tunnel extender with my existing SureFlap microchip cat flap. It fits perfectly and adds extra length for my cat to walk through. My cat now feels more comfortable when entering the house. Easy to assemble and secure on the wall.

The extender works well with my DualScan cat flap. I added two extenders to make the tunnel longer. My cat uses it without hesitation. The brown color matches my home decor nicely.
