“The animals in the Zoos in the US are not owned by Jews.”
My point is that the zoo can feed its animals basar v’chalav, and chametz on Pesach. Not a problem.
“Going into a swimming pool on Shabbos is not such an issue. It’s coming out of it where you run into trouble.”
ROTF!!!
I’m of course been assuming that this is your own private pool. Many rabbis have prohibited mixed sex swimming, for obvious reasons.
