Cats belong on one side of the door or another. They can go through doors and that's fine, but if you force a cat into a door that's likely to hurt the animal and that's not cool my dude. Please do not put your cats in doors. Let them safely pass through, beside, or between door and door frame. You may play with them near doors, but exercise extreme caution.
Thank you for your time have a nice day
When is a cat not a cat, when it's ajar
