I agree with the others’ suggestion that you get anyone over there to give her water and also some very wet greens if they can.
I’m saying this more for general advice than to you here, since you are already worried, but when traveling it’s a good idea to have two kinds of water sources available. A crock and a water bottle usually do the trick. I have come home to find a dissolved pellet, or poos, or some hay in a water crock that’s yucky as a result and it’s kind of startling to realize it’s been a while. I actually have been shopping this week on line to get a metal water dish like the kind they use for birds that attaches to the side of the cage, as a backup. I never had luck with water bottles, MM. Usually mine leak to empty too soon and get everything near them wet.
Boston will be fine – take heart. But get home safely and see if someone will go visit our girl for a round of drinks.
Hugs.
