Yea, I think the 'diluted the poison' thing is just a misunderstanding by the author of how rat bait, and rat bait treatment works. People working in 'specialist fields' like vet med had to deal with people misinterpret the details of our work, and being armchair experts all the time. You just did it yourself, assuming vit K and fluids would be enough to save an animal suffering for severe acute anaemia.

120ml is not a small amount for a cat, it's a pretty big transfusion. With that volume, I suspect the cat had a PCV (packed cell volume, or % of blood that is red blood cells) of around 10 - 15. It should be about 35 - 40 in a cat, so that is INCREDIBLY low. The vet stated the cat would have died without the transfusion, and with a PCV like that I would have to agree.

I agree media tends to sensationalise and play into collective fears, because it sells an they exist to make money. But really, the dog-to-cat aspect of this story is what's interesting, and it almost certainly saved the cats life. No-one would be interested in the other aspects of the treatment, which would include lots more than just vit K and fluids.

I think we can safely assume the cat also received Vit K and fluids. I know I've seen plenty of animals with rat bait coagulopathies that I've given blood transfusions as well. I assume you're also a vet since you're passing opinion, how does only treating with Vit K and IVFT work out for you? Do you lose many? What PCVs are you seeing pre-treatment and how long do they take to recover?
