Carnist: DON’T DE CLAW YOUR CATS! THAT’S ANIMAL CRUELTY!!
It's not difficult to understand, except by "denial logic".
Have you witnessed how they're prone to infections, needing a special litter for a while? How it's painful, causing them to hesitate even when moving from a 1in object, as if it was a high jump down? I did. Do you know that without claws, they tend to bite more, increasing the odds of infections for family members? That if they need to climb to escape from a threat, they no longer can? If meeting another type of threat like a catfight, they're greatly disadvantaged?
If you know cats, you also know how they're curious and may sometimes find themselves outside even if you're generally careful. Then if they can go outside and have their regular vaccines and flea treatments, they're generally happier and healthier.
Ironically, you sound like the type who might try to feed only vegetables and grain to obligate carnivores, due to general ignorance.
Chicken is one of my favorite foods, there I admit that I don't look at materials showing their suffering everyday, that may not only disgust me but possibly also depress me. I suppose that it's a bit like the sanitary infrastructure I'm used to. Not being a plumber, when flushing organic material, it's almost like if it vanishes into another dimension. It may not, but I hope that the city management uses the best environmental and safety practices to deal with sewage.
I recycle and I isolate the materials of the same type together to ease sorting. I try to do what seems feasible.
