* Basic door handles: Most cats can't open a standard door handle. They lack the dexterity and understanding of how the handle works.
* Lever handles: Some cats, especially those with good dexterity, can learn to open lever handles by pressing down on the lever with their paw.
* Doors with automatic opening mechanisms: Cats can learn to trigger automatic doors, like those that open with a sensor or a button.
Factors that influence a cat's ability to open a door:
* Breed: Some breeds, like Maine Coons, are known for their intelligence and dexterity, making them more likely to open doors.
* Training: Cats can be trained to open doors, although it might take some patience and persistence.
* Door type: Doors with simpler mechanisms or levers are easier for cats to open.
In general, most cats can't open a door on their own, but some are clever enough to figure it out with some practice.
