Acutally, I still don't have an idea of sizes from all of the pictures that I see posted on here. However, I'll give you a quick summary of my California Kingsnake's eating habits.
My snake is about 40 inches long and weighs around 315 grams. He has some longitudinal ridges on his back when he moves in certain ways, and I'm told that these ridges are a sign that he is underweight. I'm taking him to a vet on Friday and will ask about his size. He eats an adult mouse of 20 to 25 grams every week. When I bought him, the store was feeding him pinkies and fuzzies. I started on these and graduated him to adult mice. He was pretty hungry at first and ate very aggressively. Sometimes, he's less aggressive now.
I hope this information helps. If you know the length and weight of your California Kingsnake, I'd like to hear it.
Thanks,
Bill
