Yes, I was just reading a fiction book. There was a cat in it that no one wanted to adopt after its owner was killed. (Well, it was a mystery book.) One lady was saying, "Well, the cat is only two years old--and cats can live twenty years or longer! That's a major commitment!" At least we can legally not be responsible for children after the age of eighteen!
I'm glad we have a neighbor who can look after our pets when we need to leave town for awhile.
