First of all...
Kudos to getting your family to sniff your snakes urine! Lol
And yes, proteins and the type of food you eat can absolutely change the pH and smell of your body and waste.
That's why I have no problem with mucking my horses poop, but dog poop smell is puke worthy!
Dehydration, illness..all of those can also change the color, concentration and smell of urine.
It doesn't sound like anything to worry about..
