One of my cats, the ex-feral one, tries to open doors by holding the door knob with both paws. He can nearly get out of a locked window too, he lifts up the bottom latch and then tries to push the top latch to open it but thankfully he isn't strong enough. We have a cat flap with a lock on and he has worked out how to pop that open, we now have to put a heavy box in front of it, though he has now started shoving that out of the way (he is a big lad) before working on the lock.
If we try and give him a worming tablet in some food, he picks the bit of food up with his paw, sniffs it and then discards it. The problem is that he is a big fan of catching rabbits so we have to give them to him regularly.
The other one is pudding bowl stupid though, he chases his tail, bites it and then yelps. The wife calls them pinky and the brain.
I have never smoked a hooker!!I once contemplated getting one for an hour to do the housework because their rates are cheaper than cleaners but I didn't want to get STDs on my vacuum cleaner
