Is it only the dose? I think I read somewhere that rodents are especially vulnerable to this substance for some genetic reason. To lazy to check again. Not to lazy to pronounce my ignorance in a comment. Oh my.
I mean, however close we might treat them as, they're still fundamentally diferent animals
Since they can't throw up or burp, something that produces enough gas (More than a regular soda) could in theory kill a rat, but just make a human slightly inconvenienced, or on the same idea, you could wrap the poisson on an emetic agent to make it safer while not affecting the rat at all
Metabolic rate. The canary doesnt die fast because it is genetically sensitive. It dies fast because a birds metabolic rate is like a firecracker compared to ours.
>Is it only the dose?
I think they meant, for humans, the dose makes the poison. We would have to eat a very large amount of warfarin to have trouble. Rats get hurt from a small amount.
Poison is dose dependent, but the actual dose dependency is different between species.
