In my experience, the behind-the-scenes admin work is the hardest to find help with (especially if the organization is all volunteer-run).
This typically includes adding cats/people into the system, scanning medical records and adding those to the system, tracking which animals need to go online when, writing online bios, writing thank yous to donors, writing newsletters or blogs, social media management, applying for grants, answering emails and inquiries from the public, followups/checkins with adopters, and processing foster, volunteer, and adoption applications. And probably more, but this is the list off the top of my head!
