Savannah Super Cat
I neutered my F1 and F2 at 16 weeks. Both my breeders and vet advised that this was a good age for them to be altered to prevent/lower the chance of them having marking or hormonal behavioral issues. They were both over 7 pounds by 16 weeks and had no issues with the anesthesia, surgery or recovery. I highly recommend getting your boy altered sooner than later.
