Awww, you're so lucky! I was planning on volunteering at an animal shelter here, but I had to be at least 16 to have contact with the animals. But I would've went anyways, they just didn't accept anymore volunteers at that time. So I'll wait until next summer probably, or a could volunteer at Petsmart
Anyways, good luck!!! I'm sure you'll get the job anyways, and have fun!
Keep us posted!
