Bests & Worsts Reviews from Amazon

First, thanks to the previous reviewers who helped me select this door for our cat, Sid. We selected the Pet Door, instead of the Cat Door, because the Pet Door offers the ability to program exit times (a curfew mode the prohibits exit at night). The only mistake I made was that I accidentally ordered the tunnel extenders for the Cat Door (which is smaller) instead of the Pet Door. Once we got the right tunnel extenders we were able to complete the installation which was not difficult. That said, sawing a hole in the house, on the hope that the cat will use the door, requires some belief and steadfastness. Overall we are very happy with the SureFlap Pet Door. It took some time and encouragement to train Sid to use the door. He seemed to think we should just open the back door and let him in/out as we had been doing and was puzzled by our silly behaviors aimed at getting him to use the SureFlap door. He did not appreciate being pushing through the door though, of course, accepted all the resulting treats, kisses and praise as his just due. His initial objections seemed to be 1) the noise of the unlocking mechanism which startled him and 2) the necessity of pushing through the door with his head. At first he would enter the tunnel to come into the house, hear the loud click of the door in front of him unlocking, and then back out of the tunnel and still be outside. To exit he would paw at the door, which would swing open but hesitate in "putting his shoulder into it" to get out as it were. But he has gotten accustomed to the new protocol and now uses the door on his own. He is waiting for the sound of the door unlocking at 7 am when he is allowed out and comes in and out all day when we are at work. Although the door will allow Sid entry 24 hours he cannot go out between 4:30 pm and 7:00 am. This is great as we have Bobcats that have eaten our neighbor's cats. We prefer that he is inside before dark but we do not get home until 7 - 8 pm. So the Pet Door is great as Sid has lots more freedom and we have peace of mind. UPDATE: We purchased our Pet Door in November of 2014 and it has been working perfectly, 24/7, since then. But recently the door stopped operating. So I emailed the Sure Flap customer service department for advice on how to fix it and they immediately responded that they would send us a brand new door since we were still under warranty. We installed the new door and all is well. I so appreciated the terrific customer service and would now (more than ever!) recommend this product and this company.
