Has anyone used one of the AI powered cat flaps to keep cat spaces separate? This would NOT be for a front or back door, it would be installed on an interior door so the only animals it would have to detect are the other resident cats in the house.

I have read about them being used to prevent cats from bringing prey into the house and other unwanted visitors, but I am curious and seeking advice from other cat parents who have used these types of doors.
