I definitely can't read all the responses in this thread. I must say that about half of my ball pythons, I'd be confident allowing my 5 year old son to reach into their enclosures (he doesn't, just saying..) at any time (except feeding day or in shed), the other half I wouldn't. Their behavior doesn't correlate with feeding in their enclosures. Period. I have some that are puppy dog tame, I could literally kiss their faces if I wanted to, and others that want to take my face off, but again....that's their personalities, not cage aggression. But, as others have said, to each their own.
