Let your cats come and go as they please, with the Elite I.D. Disc Cat Flap with Timer Control. This smart cat door gives your furry friends the freedom to explore without needing to meow to be let in and out, but also includes a timer function to keep them indoors when you wish – for example, at night-time. This sturdy cat flap operates using unique electronic I.D. discs for up to nine cats (implanted microchips not compatible), which will not only help you track the whereabouts of your feline friends, but will also keep out any unwelcome visitors! It includes a handy LCD display to show key information too. Key features: Entry and exit operated by unique electronic Pet Mate ID. discs (2 supplied - not compatible with implanted microchips). Suitable for up to 9 cats. Keeps other animals out. 4-way lock control: in and out, in only, out only or locked. Timer function controls access for all your cats, e.g. to keep cats in at night. LCD display shows selected entry and exit lock status, cat location and time since flap last used for up to 3 selected cats. Individual entry and exit control, e.g. if one cat needs to be kept inside. Product specifications and additional info: Additional I.D. discs available separately below.
