Here is a smart cat flap that lets your kitties in but stops them from bringing you dead mice. OnlyCat comes with prey detection. It connects to your WiFi network and sends you an alert when a prey delivery attempt is stopped. You will have control over which cats are allowed to leave and enter. You also get notifications on entries and exits.
This smart cat door has an ePaper display. It has two LED lights built-in. It comes with a 5MP wide-angle HD camera with IR night vision. OnlyCat supports selective entry/exit and time-based restrictions. You can find out more about it here.
