The Ferplast Swing Microchip Cat Flap is an innovative cat flap with a selective microchip recognition system, ensuring that only your cat has access. Made from robust plastic, it incorporates the Wind Stopper system to prevent draughts and an effective 4-way locking system, allowing for the options of exit only, entry only, entry and exit, or total lock. It operates on batteries (not included), with a useful charge level indicator and a last passage indicator to let you know if your pet is inside or outside the house. Capable of memorising up to 32 microchips compliant with ISO 11784, this cat flap includes a partial tunnel and can be complemented with an extension tunnel (sold separately) for installation in doors or walls thicker than 6.5 cm.
