"Ingredients include water, isopropanol 20%, bitter principles, and extracts"this product is 20% rubbing alcohol! I am pretty sure this would be quite toxic for a human, wonder what it does to animals. we have to read ingredients. if it's NOT toxic to animals, perhaps just spray rubbing alcohol instead. very very cheap to buy! could be why one comment says the cats eyes ran and she drooled a lot. I would too! that's a pretty high % of a potentially toxic substance don't you think? could also make them drunk? if it's the bitter that works, why all the rubbing alcohol? it's also mostly water...first ingredient. lot of money for water and rubbing alcohol!
