When you right-click a cat you have already tamed to make it sit down or stand up it does not trigger the player_interacted_with_entity advancement criteria. The exception is that feeding a cat fish does trigger the advancement criteria. To reproduce the bug load the attached datapack, tame a cat, then run
/advancement revoke @s only cat_bug:interaction
The reason you run this command is because taming it will have triggered the advancement so you need to revoke it. Once it has been tamed and the command has been run, right-click the tamed cat. The advancement will not trigger.
