I’ve been looking into a microchip door to stop my indoor cat using the dog door ( He has a different outdoor area and access from inside) Apart from the possibility of him following the dog out, my main issue is that they all seem to only have the option of letting all animals out so microchip only effective when coming back in to stop random animals getting in the house. I don’t have that issue so wondering if anyone has found one that works in both ways? ie only lets the microchipped animal programmed in to get outside and in. TIA
