yes.
No, rat poison will not kill roaches. Rat poison is designed to stop blood clotting and the rat dies from internal bleeding.
Yes you can.
Yes.
Alligators aren't immune to snake poison, Rat poison is questionable. I imagine it'd have to be a hefty dose to take out an adult alligator though.
Its not just how much, modern commercial rat poison is an anticoagulant. To die from rat poison you would not only have to take a "lethal dose" but then you would have to be injured physically so that you started to bleed. Without such an injury, your liver will eventually metabolize all the rat poison to harmless chemicals that would be excreted in urine and sweat.
I want to know too.
The most common rat poison is warfarin. It can kill a man if enough of it was eaten. Warfarin is strychnine, and as such, deadly.
unlikely, most rat poison is an anticoagulant causing cuts to bleed freely. but get to emergency room anyway.
Well this will vary by the brand and type of rat poison, generly not much. Hence the name 'rat poison'. If your rat has eaten rat poison i would advise that you take them to the vet emedietly.
Unlikely, unless the deer is wounded. Rat poison is an anticoagulant, and can only kill if the animal begins bleeding due to cuts or other injuries. Rat poison works on rats because they fight frequently and once injured the poison causes them to uncontrollably bleed to death.
You would DIE!!
