even round knobs aren't safe. i had a pair that would work together: one jumping to turn the knob while the other stuck their paw under the door and pulled.

Mine just flings the dinger and looks at me like "your attention will be interrupted until you open this door"

OK fine I'll open the door but this is the last time.

My cat would smack the metal blinds when he got stuck in my bedroom with me while I’m sleeping.

I just love how he knew that I was sleeping and found out how to make the loudest possible sound in my house, all while staring at me of course, without even having to raise his voice.

One of my cats observed my partner turning a doorknob on the bedroom door and subsequently started jumping and pawing the doorknob when the door was closed and they wanted in. No question that if it was a handle-type knob he’d have gotten in.

We had to rotate all our handles to vertical because our cat learned in 2 weeks how to operate them.
