Ultimate proof that cats are smart !!! more smart cats«
Cat intelligence is actually a pretty interesting topic in that the majority of studies on the subject basically have to end in the conclusion "we just don’t know" because cats are among the most uncooperative research subjects of all time. We know a great deal of cat sight, having used cats as the archetype for a vision-focused vertebrate/mammal, but we still know very little about what really goes on inside the cat mind.
Adding to this, in the last few years of my two cats lives (they were sisters who died one week apart) they both learned how to open my door since they liked sleeping with me (partially cause attention, cold nights, etc). My door stays closed at night so at first they learned to knock/scratch the door to get my attention knowing I could hear it. Eventually they learned to pull the door handle until it opened.
When they did this I would hear my handle being shaken at 3am and I’d freak out only to have my cat open it and walk in and I’m just like “You fucking shit”
My cat had learned to get onto our dining room table and jump to flick the light switch on so he could saunter into the kitchen. Those bastards pick stuff up, I think they’re generally just too lazy to care since we usually do everything for them.
