I have our new kitten sitting next to me, purring so loudly I can't hear the TV.
I found him in the woods outside MILs apartment- his eye was so infected it was crusted shut, he had tapeworm, fleas ALL over him, and he was starving. MIL said the rest of his litter died. He was about 5 weeks old.
I brought him home with me, and he purred in my lap the whole way. Took him to the vet the next morning, got Frontline, all the tests, etc. & gave him a flea bath 2x a day until they were GONE.
He's an indoor kitty, sleeps right next to me, has a bowl full of clean water and food.
He was declawed (& neutered) two weeks ago. Laser declawed. He had NO bleeding, never acted like he was in any pain at all. Vet said he'd have NO pain with a laser declaw & I believe the Vet because he has shown no signs of pain.
He would still be in the woods starving to death, being eaten by fleas, eith a tapeworm and possibly dead already... Instead of purring at my feet, curled in a ball.
No one will EVER convince me that what I did was cruel. Cruel would have been leaving him in the woods to die, and I'll never see it any other way.
OP, I've had front declawed cats my entire life with no behavioral issues, no litterbox issues, or why of the other stuff I read here. So that's 6 cats with 0 issues at all.
Everyone is entitled to their own opinion, and until a cat can talk, that's all either side of the argument will ever be.
