I ordered a Treat and Train from Cat Flaps, due to be delivered by Yodel. Yodel text to say it would be delivered by 9pm. At 8pm I text and rang the courier, no reply. I tried phoning Yodel, the automatic service hung up on me several times. I live chat online with Yodel at 9,30pm, who said it would be delivered next day. They have no idea why the courier did not attempt to deliver it and took it back to the local depot instead. I contacted Cat Flaps by email who asked Yodel to return it the them and they sent me one by Royal Mail, which I received promptly with no problems. Very pleased with the prompt solution when I made Cat Flaps aware of the problem. I went and bought 4 size D batteries for the main unit and one 12v 23amp battery for the remote. There is a Quick Set up Guide, an Instruction manual and a DVD included. It was very easy to insert the batteries in both the main unit and the remote and to set the radio channel on both. Choosing the size of kibble disc and inserting /removing it is easy. Putting the kibble in is easy. Sometimes one press of the remote delivered more than one piece of kibble, perhaps need the smaller hole kibble disc. I read the Quick Set up Guide and the first part of the manual, and watched the first part of the DVD. Then I set about training my dog to use the Treat and Train as per the instructions. There are step by step training instructions which I found very easy to follow, including common mistakes to avoid. My dog seemed to take to it quite well, going to get the treat when she heard the beep, looking at me before going to get the treat. As it was our first time, she did well when we stood near the Treat and Train, but when I moved several feet away, she has not yet got it 100% of the time. But a good first session. I have not yet used the touch stick and base, which is also included, to use in the next stage in the training. I am hoping by following the training step by step, on a daily basis, that in a few weeks time I will have a calmer well-behaved dog when visitors come.
