I went and read the thread you were talking about, and no, that's not what we mean. What you got on that thread was good information that will allow you to make more informed decisions for your rats in the future. It is NOT your fault that you didn't know better, but we would be remiss in not pointing out that that particular vet doesn't really seem to have a clue. If you have a vet that you trust who sees your dogs and cats, definitely talk to her, and ask if she's willing to learn about rats. A vet who doesn't know but is willing to learn is leaps and bound above one who doesn't know, but pretends he does. You are perfectly justified in not wanting to see that vet again, and not one person here will blame you for that. You cannot blame yourself for what you did not know. At some point, we were all beginners, and trying to learn. The whole purpose of this forum is to try to cut down on stories like this, and get people informed.
When we talk about shoving info down people's throats, we're talking a large group of people all ganging up on someone, even though the info has been laid out already, and there's no real reason for 95 other people to say the same thing.
