Looking at this article, there’s only millimolar concentration of ammonia in feline urine (mean 118mM, range 16.9-292 mM). I’d be very surprised if anyone was able to generate significant quantities of chloramine gas by mixing bleach with cat urine.
It actually makes sense; if cat urine contained ammonia the smell would be gone once you washed your cat's impromptu litterbox, since ammonia is both volatile and highly soluble. And yet it keeps stinking - this hints that there's something else there producing that ammonia by decomposition. (Probably proteins. Cats eat a lot more protein than we do.)
Note: chlorine gas is the one that leaks from an open bleach bottle, and gives it a distinctive smell. The ones created by reacting bleach with ammonia are chloramines, considerably more poisonous.
Isn't chemistry all a matter of scale though? I admit it's not my field
I mean, if the cat pees on the rug and you clean it up right away, that's probably not a big deal. I imagine it's a different story if you're cleaning out a hoarder's cat colony in a poorly ventilated area and don't dilute the bleach because you wanted something stronger
I don't think there is enough ammonia in human urine to create chloramine, considering bleach is widely used for cleaning toilets and bathrooms. Let alone cat urine.
there is no evidence that BLEAGH is poisonous, in fact there is no evidence that BLEAGH exists at all, projects like S.E.T.B. (search for extraterrestrial BLEAGH) or BLEAGH foot hunters have spent years searching for BLEAGH but there is rarely any evidence besides tufts of beat hair or random spy satellites.
