Info on early spay/neuter?

Hey, Can anyone throw me some links for info on early neutering? Would be much appreciated.

and yes, I know how to google the problem with that, is I want info that is correct, and recommended, rather than info that may not be correct, etc.

Thank ya muchly.

This is from the clinic where I had Jake neutered. It is a really small non profit clinic that isn't all that famous, but the vet started this with her own funds after quitting her job at another clinic, I think she's an amazing person. I really trust this vet, her recommendation for shots for indoor kittens is to do two sets as a baby then at one year and then never again which is exactly what I've come up with after my researching on my own so I am really glad about that and for that reason I have huge trust in her. But I can't really vouch for how correct the info is, except for on the second link you can find some pics of when she has done pediatric surgery vs. adult

OH AND THIS IS IMPORTANT!!! If you don't like to see blood don't watch they are graphic images.
