Oral and Intraperitoneal Administration

I would personally first ask the mice if they actually want any quercetin at all; if their answer is 'yes', then I would ask them if they prefer oral or intraperitoneal administration and how much quercetin they are willing to receive. I would give them an unlimited time to decide and allow them to revoke their initial consent. Finally, I would ask them for a written statement of their voluntary participation in the quercetin experiment . . .
