I love to volunteer at animal shelters! Have you ever volunteered at an animal shelter before?
yes, in the past.  I volunteered at a no-kill shelter.  
That is awesome. Animal shelters are always in need of good volunteers, people who really care about animals.
Many countries in Europe do not allow organizations to kill healthy stray animals.
I wish the United States would follow more after Europe in that area. There are so many strays killed needlessly every day unfortunately.
In the US," animal shelters" is a euphemism for pounds.
A pound does not sound like somewhere I would want any poor animal staying! It's such a shame isn't it?
Animal shelters are generally good and not for profit.
