I’ve always thought of cats as rather evil creatures, since they don’t seem to treat their masters right and always have a mind of their own. Whenever they’re in heat though, they tend to go nuts and enter and leave your home as they please via the catflap. Put your foot down and prevent your pussy from being the village bicycle with the RFID Catflap. Since it uses RFID tags that allow access to the flap at specific, pre-programmed times, you don’t have to worry about having your kitty having a whole lot more happening sex life than yours.
