well even if you don't have much time, maybe you could keep animals overnight for whatever reason, or be a foster owner for a week or however long you wished, or maybe just cleaning supplies or food. i know the shelters here appreciate any help someone wants to give even if its not time at the shelter and either supplies, food, or cash to pay for other things. i really wish i could help at the shelter close to the house but im pretty much full time taking care of someone and don't get much (not that i need anything considering who it is) out of it.
