What kind of job can a 14 year old get to do with animals?

I used to pet sit at 14
you could help out on a hobby farm if you are in a rural community.

You could possibly volunteer at humane societys or see if you could help at pet shops, not doing anything serious or what not, but otherwise you may have to wait until your a bit older. So sorry about your mysterious infection!!! I hope you get better really soon!!! :'(
