California Kingsnake - Ready for Fuzzy?

[Seemoore57]

I have a California King that is 33 grams and about 21 inches long. I have been feeding him pinkies since I got him, starting at two and slowly working my way up to three. More recently, I noticed that when I fed him pinkies I couldn't see any bulge in him, which I believe I read somewhere means that the food is possibly too small. I went ahead and attempted to feed him four pinkies since he so easily ate three. He ate them very happily and even after four pinkies it seemed he was still hungry, and didnt even show a bulge. I want to move on to fuzzies since pinkies dont seem to be doing the trick.

I've always heard a good rule of thumb is to match the size of your snakes food to about its widest point. It seems that the fuzzy I thawing out is just a little bigger than his widest point, but I can not even fathom him being able to eat it. His head/neck is just so small! Is it safe to feed him this fuzzy? I would say that this fuzzy is just a little bit bigger than his widest point.
