How worried should I be about refilling/washing my BP's water bowl in sinks that humans use? I live with 3 roommates and we share the kitchen and 1 bathroom. I'm assuming the kitchen sink would be a big no-no. And I'm concerned that roommates might use the sink in the one bathroom for face washing and such. The bathtub seems like it might be the best option? Would I need to clean the bathtub every day to avoid bacteria getting on feet in the shower? And should I be concerned if someone wants to take a bath? There's also a more secluded washing sink in a storage room in the basement that mostly just gets used for hand washing and tooth brushing, but I would hate to have to go all the way downstairs every day just to refresh her water. Thoughts? Are there options I'm not thinking of? Where to do you wash/refill your water bowls?
