I am told that adding blood to the diet makes the kitties throw up. It is ok when blood is present in the meat, but not to add extra into the meal or as a treat.... This is my understanding, at least.... I see no reason to it. What is your thought? Are you thinking to give more iron to the kitty? Is that the reasoning behind it?Do you guys think blood is good for cats? Those of you who feed frankenprey, do you include blood in their diet?
I'm told that if you don't bleed the meat properly, it'll spoil. . .I suppose that wouldn't matter if you were feeding it fresh, but if you want to store it that would be a factor. And I don't know if it would still be suitable for animal consumption (just "spoiled" for humans), or if it really goes bad if the blood is left in. Or how fast it would go bad. Usually most of the blood is lost in the butchering process, though.
I'm sure there's a home butchering website somewhere that explains everything.
"Meat juice" isn't blood. It has some red cells in it (which is why it's red) but is mostly water leaking out of the meat. You probably notice that it's a lot thinner than blood. So a kitty could lick that up without getting an upset tummy like they would get from drinking straight blood.
ETA: Oh, so he does bleed the meat but captures the blood. Eww, no, I wouldn't, for many different reasons. But even without other reasons, I think feeding it separately (not in the meat) would probably make the kitties sick. And cleaning up blood vomit would be really disgusting. . .
