my snake lost a little bit of tail when i first got him. When I say a little I mean just the vry pointed part, less than a mm probably, but it was due to a small shed piece that I just could not get off. No one can even tell it ever happened, not even the vet, but it just goes to show that what they say about stuck tail sheds is true. If that shed does not come off you will have a snake with no tail.
