You should really be replacing those knobs with levers. Knobs are an accessibility barrier (e.g. for people with arthritis or motor issues) and they're also just a pain in the ass if you need to open a door when your hands are full (or when said knobs are slobbed).
my lever is actually an obstacle to accessibility because my fucking landlord installed it upside down
(not OP) My only complaint with levers is that I snag my pockets on them. This might be peculiar to my pocket-height. Is there a more accessible door handle style that is less snaggy than levers? I'll do me a web search.
Also, jerk cats can figure out how to open them. Then again, what sort of monster would try and keep a cat out of somewhere /s
Sidenote: I bought my condo from an elderly lady and I love the accessibility features that were installed for her: night lights all up the stairs and in the upstairs bath, really sturdy grab bars in the bath. I highly recommend bath grab bars.
