I am going to apologize in advance. I am so sorry that this is long and image-heavy.
Ugh I hate the whole "keep our breed pure" propaganda that I see when I go online searching for dog images. Like these ones.
I know this isn't to the extreme of tail docking and ear cropping, but it's an example of how messed up the idea of "pure breeds" is. It's a coat colour. It's not some big dis-figuration or dangerous genetic mutation.
I also hate seeing people breed pure breds to the "show standard". For example, I love German Shepherds. But "white" German Shepherds are disqualified in most countries.
That, and they have an unnatural, sloping back. This causes hip displasia. I'm not entirely sure, but I believe that a sloping spine is required for "show", and anything else is not to "breed standard".
Then you have flat-faced dogs.... just no.
They're not cute. Not to me. And not to the people who know how bad it can be for dogs to have such a flat face.
This is not quite the same, as it's not breed-related, but it's on par with tail docking and ear cropping.
It's just so unnecessary and incredibly bad for the cat. Side effects vary for individuals of course (I know a declawed cat who may be a bit touchy in the paws, but otherwise he's not so bad), and then I read about cats who try to avoid walking for the rest of their lives, cats who get deformed paws, cats who get severe arthritis from having to walk wrong, etc. There was even a story from a person who worked (I think with tech stuff) at a vet's office, and witnessed a cat thrash so violently in its cage after the procedure, that it broke its own neck. There are even some vets out there so twisted and sick that if only two paws are being declawed, they don't give the cat anesthetics. Some vets don't even put the cat's under completely, so they're partly awake during it.
For anyone who wants to learn more, here's a link to The Paw Project -

They're an amazing organization, with a movie on Netflix about declawing, a facebook page, and lots of info on why it's bad, and alternatives you can choose from. Like with tail docking and ear cropping, sometimes declawing is for the good of the cat, say to remove tumors. But it shouldn't be to protect your furniture. And don't try telling me it's to protect your kids or something - a cat's bite is a lot worse than they're claws, and trust me when I saw, declawed cats bite when threatened, instead of wack you with a paw to say "no". If you don't believe me that a cat's bite is so much worse, here's someone's account of their experience with a bite from their pet cat
