Review on SAFELON Safety Stopper Convenient Adjustable by Jeremy Ward

My cat likes to go for a walk outside in warm weather (too old and slow to get out of the garden). But if she wants in or out she has to go through the dog area (they are fine but eat their food going upstairs). That works great! Keeps the door open for her to move freely, but keeps the dogs from eating all her food and trespassing on her property. I used the Stick app and it was very easy. May not work for large/fat cats but is quite small and narrow. The best part is that it keeps the opening at a predetermined distance. Some of the other retainers allowed the door to be partially or fully closed accidentally.
