Any evidence in this article that the woman was planning on bringing sick animals into a clinic to trump up a claim? Nope.
I'd agree with you that there are *way* too many people in this country looking to use the court system as a way to cash in.
However, I think it's also human nature to (over)react to problems once they've been identified. It's entirely possible that many pet owners are now simply hyperalert to any problems that their pets may exhibit.
Keep in mind, too, that when people are scared, they do stupid things. I can cut some slack for the honest people who are just scared for their pets --- but I have no tolerance whatsoever for people who would knowingly attempt to bilk someone out of money through a bogus lawsuit.
