If the cat has constant trouble with the station's competitors, who come to the home afterward, then we recommend these chip-controlled cat flap that only let in the house Stubentieger. We can install the cat flap of a glazier, because in the conservatory had to be replaced with a small plastic box. And then off we went: Programming was absolutely simple, because the hangover came curiously at the close and triggered the read-in mode. Only: it really took almost 4 weeks until the critters had understood how it works. With endless practice and treats it has finally succeeded in that they have accepted it.
