I bought this RFID chip activated cat door from Amazon a few months ago and then, after my cat got beaten up by the neighbour cat, I decided I no longer want him to roam in and out. These two items were sold separately, took a long time to arrive, and were never opened. How it works: If your cat or small dog has an implanted RFID chip or one on its collar, you can program the cat door to recognize it and unlock when the cat/dog approaches, keeping out unwanted animals. Car door sold for $141 https://www.amazon.ca/gp/product/B00MIRNPHI/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&th=1 Two tags sold for $30 https://www.amazon.ca/gp/product/B09VVMKFXT/ref=ppx_yo_dt_b_asin_title_o01_s01?ie=UTF8&psc=1 Selling together for $125 - never opened. I live in Shawnigan but could deliver in Victoria. Email/text only, and I'll remove the ad once sold.
