BK here is cheaper and wayyyyyy better than McD. So weird when people say "at least McD is consistent" - that doesn't help if "consistent" is inedible garbage.
That's not a crazy idea. Go ask your sis. Catss unlike dogs, have blood vessels and nerves in their nails so you can only safely trim them a few mm. A scratching post or something similar gets the job done in a safe way without trimming.
They couldn't loop around really. And you can only trim the very end of a cat's nail without injuring it. If it's purely a indoor cat just give it a few ways to scratch their nails and everything is fine without ever needing to trim the nails.
Oh I guess I have to quit my job then :(
