I'm going to withhold my opinion of this woman (public forum and all) BUT every vet I know provides euthanasia at no cost.
I am one who has spent unexpected large sums of money on my dogs, cats, horses, whatever (and it is ironic that my horses are less expensive on vet bills AND food than my dogs). I will always do so where necessitated. And I don't believe that pets are a luxury. They fill a part in the lives of the people that love them that is no less necessary than any other relationship. The people who died during Katrina because they were not able to take their pets with them are pretty much proof positive that many people feel the same way.
I don't believe anyone should be parted from a loved one due to financial need. My dream is to start a not-for-profit that provides homes for pets when their owners have suffered health issues and cannot care for them (the elderly, disabled, terminally ill). If visits can be arranged, they will. If the pet can stay in the home and volunteers can provide daily care (walks, grooming, feeding, vet visits, etc), they will. If their person passes away, they will know that they will have a loving forever home. And if someone can provide a loving home but can't afford the medical bills for their furry family member, there will be help also.
Just a dream, but I've seen and heard of too many stories of people having to "give up" their pets due to health issues or financial need. It's rarely ever a good result for human or animal. I can't say that someone who suffers unfortunate circumstances is any less worthy of sharing their lives with their cat/dog/etc. If you can't afford them and neglect them for that reason, that's a different story. But I'd sell plasma to pay for my critters' medical care. Heck, I'd probably do it for yours, too.
