How much can a snake pee?

[Blue Apple Herps]

The bigger the snake the bigger the waste, at that size they can produce enough urine to soak an entire tub, the white part is urate (urine bi-product), obviously fecal matter would be dark brown and can contain small or large amount of fur in it.

Yup. It's pretty remarkable just how much they can have stored up. There are a few super huge girls I have where they just unload an ungodly amount of waste.
