Door blocker for cats

My cats have figured out how to close doors on themselves, which they most enjoy doing at 3am and then making a huge racket to let me know they are stuck in the bathroom so a couple of these blockers to put on bathroom doors to prevent them from closing enough to latch. These should be good for either right or left handed doors.


They are attached to the doors using 3M command strips however you can used two sided tape easily, printed with some extra bright PETG I had laying around.

Also important:
you need to space it correct to ensure the end of the latch isn't too far inside the door as to give the door frame a pivot moment which can untape/velcro the pivot from the door frame if you look at the pictures it should be pretty self explanatory for the spacing.
