Maybe whataboutism here but there are beagles in the UK right now waiting to be experimented on them (possibly for a new dog food brand) and eventually killed. There are billions of animals all around the world dying a slow and agonizing death, trapped in CAFO facilities right now, of whom 20% alone are getting fed to dogs in the US.
I think some cat getting fed a well formulated vegan cat food containing taurine, vitamin A & D3, omega 3 & 6, magnesium, copper, iodine, selenium, manganese, zink & calcium is astronomically better off than any aforementioned animals.
I fed a cat I had to take in for some time the AMI brand. She was wild for it.
I'm not sure if I understood your deduction. The literal translation of "Zange" would be "tongs", "pliers" or "pincer". Hinges are the things that make doors swing and hold to a wall right?
Multiple source say the origin of the word isn't documented but the best explanation they come up with is that pliers can be used to bend something into a different form.
My guess was it has its origin in the proverb "Das würde ich nicht mal mit der Kneifzange anfassen" which translates to "I wouldn't even touch that with pliers" as in stuff you detest that much that you rather would stay away from it.
