What size drill bit did you use to drill the holes for the machine screws? I don’t think you showed that part? My directions said to use 1/4”, but the screw sleeves they provided don’t fit in those holes and I’m worried about drilling too big.
The dogs quickly found that they could come and go as they please. I like the cover. When its on they know they cant go out. They can visually see the its closed. Dixie, our female , just brought in her first squirrel. My wife was not happy. :-)
The door is small. I don't think anyone could fit through it. Maybe they could reach through, but this door is next to our bedroom so if we are home we would hear it. It comes with a cover that goes over the door also.
I would not think so, at least not without some modifications. It attached with bolts through the door so I'm not sure how you would do that with a sliding door
