Also remember your four legged creatures that are outside. Birds can use bird baths to make sure they are hydrated and have a place to cool off. Your outside pets need access to shade and fresh water. There's no such "just a few minutes" and not making arrangements. People get distracted and a few minutes can easily turn into 30 or an hour or maybe longer. That's too long to not have provided shelter/shade and refreshment for your pet.
