I haven't used Windows in a few years (and never used OneDrive), so pinch of salt time, but...
I don't like the idea of M$ having direct access to all of my files and personal data
That and, there have been mishaps with OD deleting files
Also, i personally don't like software automagic, especially when i don't understand what is going on under the hood
Is OD just a folder? Where are my documents actually stored? What happens if my internet goes out? How much do i trust M$ to not bungle something or sell or leak my files?
Be calm, gentle, but firm. No build up, no "I'm sorry kitty, don't be mad" and try not to be tense. Just do it. (If you're tense, they're tense)
Use a treat or food to distract the cat, and hold them firmly (preferably, have a second pair of hands, but I manage just fine on my own)
Proceed with the processes, even if the cat complains, or gets a little feisty (back off if they're ballistic). Let them know (with your body language) that you're not stopping because they're unhappy
Also, make sure they have a good footing. Cats get uneasy if they don't have their feet on something, or if the ground is slippery (like a bathtub)
Put a towel in the bottom of the tub to give them better footing (not the best solution, but it works)
Cats really only like to scratch on tall and sturdy things like trees or heavy couches
If their post isn't tall enough, they can't get a good stretch out of it
If the post tips over easily, they just won't want to use it (you can also use a heavy weight to keep the base steady, but I find that solution rather cumbersome )
"Don't feed the trolls" is a Golden rule of the internet,
However, providing well sourced and constructed counter arguments can be good for anyone else following the chain
The trimming in the pic is perfect. You can clearly see the quick (the opaque bit of the nail (in the shape of a triangle), before the nail starts curling) is about 1 or 2 mm away from the edge
If the quick was cut, there'd be blood, and a very pissed cat
I've got tons of cat scratchers, the ones that are very tall, so the cat can get a full stretch, and have a wide base, so they don't fall over
And 2 of my 3 cats still need nail trimmings about every 3-4 weeks. Otherwise their nails get stuck on things, or they claw me to death by accident since their nails are so long, they don't fully retract
My dog's nails, I have the vet handle, because I cannot trim black nails without hitting the quick
Edit: here's a link to the scratching post I use and recommend
Most of the time, it's me
Even medicated, it's impossible for me to keep a normal sleep schedule
I think of it as compensation for waking up at noon every day
