How do you tell if urine has gone bad?

I have some coyote urine from last year. I didn’t freeze it. It was left in an old cooler all spring, summer and fall. I think it smells like urine with just a hint of poop when I squirted it.

Do you think it is bad?

Not sure without taking a sniff BUT I have salvaged bad urine like that before by adding some skunk lure or IF you have some skunk essence to it.
It doesn't take much and while you lose your urine, you have gained a squirtable call lure. Try it.

You might get a digging reaction instead of a urinating response from it. I always say, when in doubt, throw it out.

Hows the texture taste? If its still smooth you'll be ok.

Urine that’s turned will have a sewer, septic smell to it.

It’ll also take on that milky gray color like sewage water.


I wouldn’t toss it. It’s not totally useless but I also wouldn’t use it as I would good urine.

Agreed. I told this story before but...I went to my first Fur Takers convention back in the late 80's with my father-in-law, it was in Bardstown, Kentucky.(?)
Ludy Sheda from Iowa was there selling his goods. Ludy would sell almost anything for a dollar. But he did help trapping a bunch by auctioning
off items when needed for the trapping associations. He also gave kids free stuff too. Anyways, I was greenhorn and didn't know much. I walked up to Ludy's
booth and needed some predator urine for my trapping. Ludy just so happened to have a "special" on Bobcat urine. it was much cheaper that his other
urines, so I bought a gallon. I was a proud trapper and showed my Father in law my purchase. We wandered around a bit and just so happened to be
near Ludy's trailer again when and I see one of his workers zipping up with a jug in his hand. Yep, those jugs were labeled bobcat urine that were on sale. I was hot
and embarrassed! I took that jug back to his booth and demanded my money back....Ludy offered me a beer grinned and said, " Buyer beware." I took
the jug home set in on a shelf and wondered what to do with it. I ended up pouring an ounce of a skunky lure in it shook it up and used as a long distance
call lure at different trap site, ie. brush piles, fence posts, rock piles.

Like Boone stated, typically unclean urine or some that is going sour, will begin to smell like a sewer water depending on what stage of age it has, it will also begin to stain your plastic container if that is what it is stored in.

Urines can change odor if exposed to high temps for extended time periods, particularly in plastic and if they already had some bacteria from the collection process that wasn't filtered out well enough before bottling. Glass containers are better for long term storage.

I would have went out and added the gallon to his gas tank.

Lol BC!

He would have worn it if he admitted to me he sold it intentionally.
