Maybe try contacting Ten Lives Cat Rescue, check them out on IG. They do great work, but not sure about if they accept minors for volunteering.

I volunteer at pawswatch community cat center in Johnston, we do allow minors to volunteer but duties are limited to anything that is NOT opening cages/cleaning cages/changing food/litter

Some rescues and shelters look for volunteers to socialize with the cats and get them acclimated to being around people. Basically just sitting in a room with them, which is something minors should be able to do.

Don't take it personally if you get rejections. It's almost always for safety - and probably insurance - reasons.

Years ago, I filled out a long application for a RI city animal shelter, I checked off I was willing to pick up and clean animal poop. Never heard back. Who says no to someone willing to volunteer to pick up animal crap???

I was going to suggest that place, my aunt runs that shelter!

I believe Westerly Animal Shelter has minor volunteers if you’re in So County

I don't know if they have a ton of cats but https://heartofri.org/ has been looking for volunteers

I love that place. Helped us with some feral kittens we had come to our house.

RISPCA

Can't say as a minor but Ten Lives has been a home run for the two we've taken in

Is there an age limited in the states to when you are allowed to volunteer? In england shelters like the RSPCA are happy that any age can volunteer but do state that under 16 that there will be a limited type of work.
