Pine, exatcly as I did, because we have developped an immunity to them precisely by previously being bitten and scratched, however when one of my friend who is not usually exposed to cats got bitten, she got an infection.
Being clean does not mean being free of bacterias, every animal carries bacteria in their mouths, and what is harmless to one species (or one individual) is harmfull to another.
Cats will not directly contaminate a glider just by living in the same space, if the gliders get bitten however, it's another matter, which is why I said that I doubt those would be dangerous if ingested, but better be safe than sorry
