6wks is to young. 7wks is a good age. I gave my cats kittens away at 7wks because they were only nursing for the fun of it. 12wks is way to old so don't wait to late. I once had a cat I got at 9wks and she was the best ever. Let your cat go outside. That's what they like. Make sure you spay or neuter at 8mo. That's the healthiest age and it's the most effective. Don't declaw either. They won't scratch the furniture if the can go outside and scratch trees and earth. Collars are nice. Don't use the release type because they loose them non-stop. I'd put an ID tag and rabies tag on too. Some people like the type w/elastic in them. Make sure to give your kitty lots of love and attention. Some cats appreciate a cat door. You don't have to deal w/a litter box if you use that! Hope that helps>^.^<
