This is my second ball python and I am fostering him/her for now but will likely adopt. My previous Ball Python was rehomed due to an overseas move. I do not know the sex or age or any history on Zipper. I saw him eat a medium rat when I picked him up and he is very docile. He is 3.5ft and 1678g. Does this seem about right? Do you think weekly feeding would do or maybe every 10 days? Is there any way to tell the age? He also seems to be a bit darker in color than other Ones I have seen. I will try to post a picture
