Really though, if the rat isn't happy living with other rats, or with the company of people....what kind of life is he looking at anyways? Rats are highly social - I know several rat fanatics who have had rats PTS rather than have them live solitary lives. What difference does it make if the rat was bred for snake food or not? Rats that were bred to be feeders make fine pets.

Perhaps what you should be objecting to is the encouragement of live-feeding. Maybe making a counter-post about the benefits of a frozen/thawed diet for snakes would have a better effect. I can provide you with some gruesome linkks on the topic; if you are interested, PM me.
