Common questions
How many pets does the PetSafe door support?
Up to 40, the highest capacity here, which makes it well suited to large multi-pet households. It also supports programmable collar keys for pets without a compatible chip.
How good is the weatherproofing?
It has the best seal among the cat flaps here, a dual auto-latch and energy-efficient sealing flap that held out wind and rain in testing and kept indoor temperatures steadier than standard models.
What is the catch versus SureFlap?
Pets need to be within a few inches for reliable scanning, where SureFlap's wider read-zone catches them sooner. Slower cats can occasionally trigger a delayed response.
