Do smart pet doors actually keep raccoons and stray cats out?
Reviewer consensus
Locking, sensor-activated doors are dramatically better at this than passive flaps. Specialist-community threads on r/homeautomation specifically call out SureFlap DualScan and other RFID-locking doors as the main way to stop raccoons and intruder cats. No system is perfect, however, and r/Pets threads describe persistent intruder cats that learn to wait out the lock cycle.
