Maria,
I love this "problem" you're having. So amazing to see so many people wanting to help.
Is the issue solely onboarding large numbers of groups? Or do you not have enough opportunities for them all?
If the issue is the later, do you partner with other local organizations? You could identify likeminded organizations who also would be a future foster/adoption base and share Volunteers. It could be a youth group, a mentorship organization even another local rescue/shelter or Veterinary clinic. Events are also an amazing place to have volunteers share their skillsets as well.
Good Luck!
