Suddenly the rat poison I put in my Rhino shelter is disappearing. A
couple of times I've seen some missing and then sick mice crawling

put out a new box and the next morning it's all gone. What is eating
all my rat poison? This could get expensive.

If it's Warfarin, it doesn't kill right away. Maybe several days.

Or generations.

I forget which.
