Hi! I volunteer at a pet shelter on the weekends!
Oh great! Even though there are no-kill shelters, sick animals and animals that aren't claimed get euthanized.
Really? How does that work?
Animal shelters include surrendered, abandoned and sometimes sick or wounded wildlife.
Do the shelters try to help the sick or injured animals?
Well, in Europe, most countries permit the killing of healthy stray dogs.
Do the shelters get really crowded then? 
The term "Animal Shelter" was previous known as a "pound"
That's interesting because shelter makes me think of hope and pound sounds like a jail. Brilliant to change the name.
Some shelters even have tropical animals.
