@ItalianPrincess1217, the Humane Societies are (almost) always in need of people to help out, whether it be with administrative duties, dog walking, or cat socializing.
Plus, you get to play with animals. How awesome is that?
If you don’t have regular time openings, however (i.e., every other weekend), it might be a better idea to foster an animal.
HSs often have animals that need to get away from their kennels to recuperate—kennel cough and URIs (upper respiratory infection) are very common, and only take 2–3 weeks of recuperation and medication to get an animal well enough to be adopted out.
If amputees and injured animals don’t gross you out, animals that have recently been operated on also need someone to take care of them for a few weeks, to help them build their strength back up and lavish love on them.
Some shelters also have animals that get freaked out by being cooped up in a kennel (who could blame them?) and send these animals out to calm the f**k down. These animals (usually dogs) stay with you, and potential adopters visit your home to see if it’s a match or not.
My mom and I have fostered many times, and our animals always get URIs or kennel cough. Always. So if you decide to do it, make sure you ask for medication right away.
I’m sure I’m forgetting some things; make sure you attend classes and/or orientation if you decide to foster or help at your local HS.
