What Age Can I Get My Cat Declawed?

Before I get the hate answers “its cruel” or “its like chopping off your own first knucle” stop.
I get it, people have their opinon on the subject. And my opinon is I think its fine. I’m concerned about the healing process, which is why I’m opting to do the little bit more expensive process of laser removal, which is safer & less painful, but I am getting my cat declawed. He is 3 months old right now. What age is appropriate to get it done. I’ve called three vets and got three different answers: 5 months, 6-9 months, and 1 year. So which one do I go with? Isn’t it true the younger they are when they get declawed/nutuered, the quicker and better the heal? Thanks
And again, I get it, you have an opinon about this. But I really don’t wanna hear your opinon unless its gonna be helpful towards my question, such as better ages to do it at, better ways to do it at, and what I can do for my cat afterwards to make him comfortable for the healing process. So simple “don’t do it. Its animal cruelty” will not be appreciated. Also, to put everyones minds at ease, he’s an indoor cat & always will be one.
