SureFlap is a white, battery-powered microchip cat flap that unlocks for a recognised cat on entry, with a 4 3/4 in (12.1 cm) high by 5 5/8 in (14.3 cm) wide opening.
When a cat flap gives outside animals access to your home, it can be difficult to manage which cats come inside. SureFlap is designed for selective entry: it reads an implanted microchip as a cat approaches from outside, then unlocks for a recognised identity. Its collarless operation makes it suitable for cats already identified by microchip, and its manual settings give you a way to manage entry and exit through the flap.
SureFlap uses RFID to read a cat’s implanted identification microchip and unlocks for stored identities on entry. It learns your cat’s existing chip with one-button programming, without requiring a collar or tag for a microchipped cat. The memory holds up to 32 cat identities, so the flap can be programmed for multiple cats in the household. The entry scan is intended to prevent unrecognised feline visitors and other animals from coming in.
The stated cat door opening measures 4 3/4 in (12.1 cm) high by 5 5/8 in (14.3 cm) wide. Compare these opening dimensions with your cat’s size before choosing the flap. The clear plastic flap measures 5.59 in (14.2 cm) wide by 5.39 in (13.7 cm) high; the opening is identified as the smallest area the cat needs to pass through.
The white cat flap can be fitted in a door, window or wall, and is designed to slot into the hole made for many existing cat flaps. SureFlap accessories are available for installation in doors, windows or walls. Its modern design is made to sit neatly within a home, while the robust door and locking mechanism are designed to deter persistent intruders.
SureFlap runs on four AA non-rechargeable alkaline batteries, which are not included. Battery life is estimated at up to 12 months, depending on use. A low-battery indicator flashes red when the batteries need replacing soon, giving you a visual prompt to maintain operation.
The four-way manual lock lets you set the flap to different combinations of entry and exit, including locking movement in either direction. This gives you manual control in addition to the microchip-controlled entry. The product also comes with a three-year warranty.
SureFlap is suited to cat owners who want microchip-based entry control for one or more cats, with capacity for up to 32 identities and installation in a door, window or wall. It is designed for cats whose microchips are compatible with the stated formats; cats without a chip need a separately sold programmable collar tag. Its defining fit is a microchip-reading entry flap with a 4 3/4 in high by 5 5/8 in wide opening and manual four-way locking.
Q: Which microchips does the SureFlap microchip cat flap recognise?
A: SureFlap microchip cat flap supports 9-digit Avid Secure, 10-digit FDXA and 15-digit FDXB microchip numbers, except codes beginning 000, 010 or 020.
Q: What size is the SureFlap microchip cat flap opening?
A: The SureFlap microchip cat flap opening is 4 3/4 inches high by 5 5/8 inches wide, or 12.1 cm by 14.3 cm.
