Ball python neglect help

[Bogertophis]

There water does get changed daily because even though they didn't show signs of mites or I didn't see mites they definitely have them so water changes is daily right now, but if it's better for the vitamin to do it that way then I will,

The calcium powder I tend to just rub a bit into the butt end of the rodent.
They are f/T I was breeding my own rodents but the dust from them wasn't doing my own health any favours so had to give that up.
He has a great food response I went to change his water today he thought it was food and bit me lol I think everything we was told about how he wouldn't eat rodents etc was just rubbish and it's just blatant neglect but it's all evidence against him for the case against him if they intend to which is very likely.
Thank you though for all the advice iv had neglected animals in my care before but never this bad I cried when I saw him.

It's just that you'll get more of the vitamins INTO the snake this way (oral cavity of the rodent). You might have to pry open the dead rodents mouth a little so be careful, their teeth can be sharp.

If you know a snake definitely has mites, you need to address that quickly- they can multiply exponentially (NOT kidding!), & overwhelm (kill) a snake, just by the "little bit of blood" each one sucks out. Mites are also thought to spread disease among snakes.

It's so awful, the way some ppl neglect & mistreat animals.
