Then I guess it's fine to answer. There's really no 'hygiene' to keep track of.

They don't sweat, bleed, or do anything that humans would do that would be considered hygienic or otherwise. They can get dirty from outside influences like water/mud/etc and can clean that off if that's what you mean but that's about it.
