Four configurable lock modes to control your cat flap - Mode 1: Fully open The cat can come and go at his will without any restrictions. - Mode 2: Locked from both sides Slide the bottom locks to secure the flap so it is locked from both sides. - Mode 3: One-way exit (outgoing only) Cats can pass through, but cannot go back in; prevents entry by other cats as well. - Mode 4: Exit-only from outside Cats can leave via the flap from the outside, but cannot re-enter through it. Key benefits and use cases - Flexible access control Quickly adjust how your cat handles outdoor access to fit changing needs and routines. - Prevent stray or unwanted entries Use the one-way modes to limit entry from other animals while still giving your cat freedom to go out. - Simple operation The four modes are configured by sliding the bottom locks for reliable, hands-on control. - Practical scenarios 1) Household with multiple cats: grant your cat outdoor time while blocking intruders. 2) Weather or safety periods: keep indoor cats indoors when needed, yet allow occasional outdoor access. 3) Routine management: allow outdoor exercise during the day and secure the home at night or during chores. Notes - Four modes are selected by adjusting the bottom flap locks. - This description preserves the original function and modes without adding new specifications.
