Our animal shelter has many volunteers to take care of the animals that are stray lost or abandoned.  I am proud to be one of them
That is good of you! Is it a no-kill shelter?
Its an adoption shelter, although some of the animals do get sick and euthanizing is sometime a polity on such animals
I agree, it is immoral to force a suffering animal to live. I wish the same applied to humans as well.
Back in the day, we just called a shelter a 'dog pound', however current times call it an 'animal shelter' 
Yes I prefer the latter. Dog pound sounds very inhumane!
I was not aware that even some shelters have sick tropical animals they take in.
Neither was I! Where do these animals come from I wonder.
