Thank you very much for very resourceful instructions!
So the formula is a compound of effective agents then?
Attractant: fish oil
Floatant: dry dog food or pieces of bread
Edible: fish-based cat food
I'm soooo tempted to mix this up to experiment how bad the odor is, but my family could get kicked out of building for this... I should test it at the door step of someone I really don't like
Where I live, only oil available stinky enough are squid oil and worm oill. Then there are anchovy dry powder and shrimp powder.
My god... I could vomit just by imagining the end result...
Anyway, I try to get hold of IV bag from my friend working in hospital, and continue searching for real fish oil.
