What I Check Before Buying

Before I buy any cat door, I always check a few important things:

I avoid sharp edges and weak flaps. My cat’s safety is always my first concern, so I want a design that is smooth and easy to use.

Features I Find Most Useful

From my experience, these features make a big difference:

  • Locking flap: Helps me control access.
  • Magnetic closure: Keeps the flap from swinging too much in the wind.
