Like the subject says, GF's cat urinated on my bag of slings, combination of nylon and spectra inside a nylon bag. :evil: GF took the whole mess to the laundramat and washed them with detergent before I got home. Now they only smell slightly like kitty-wizz. GACK! Anyone think the wizz/wash cycle had any ill effects on my slings (aside from the smell)?

you could always use the slings and stuff for cat snares... sorry I can't answer your question, but I would be wondering what effects, the actual cat pee-pee had on your gear, cat pee glows under black light.. anything that glows under black light can't be that good for your gear.... :wink: might be a good way of testing to see if its all out??? GL!!

This is a pretty uninformed post, so it probably won't help... I've heard that the acidity of urine degrades nylon and will make it unsafe. Human urine ranges from PH 4.5 (acidic) to 8 (slightly basic). I don't know if cat urine is the same. At the moment, I can't find any data on Ph levels that cause damage to nylon or spectra. I've also heard that the acidity of urine isn't really enough to do much damage. Very helpful, huh??

Perhaps consult a veterinarian. Ask if there is a high acidic factor to cat piss or something else that would affect the strength of nylon. Also, I know the smell sucks, but I don't know if washing slings with laundrymat detergent is the best idea. I think it may be a little too industrial-strength.

Chop it's tail off and use it as a sling. Stupid cat.

rock_raptor.... thats how you make a cat sound like a dog... *wooooof* sorry couldn't resist. The magical ingredient that makes the piss glow is amonia.... I don't know the concentration... actually I don't know a whole lot more about cat piss than that.....

Someone mentioned a report to me once, claiming that urine on nylon is a lot worse than stepping on it with crampons. Since I don't have a source for the information, and the urine was probably human, this information is probably pretty useless to you. Personally I would retire the gear (and probably the cat as well) unless someone can come with convincing arguments that it is safe to use it. hellclimber

I say that if you don't trust it, toss it and it sounds like you don't. Or a better question. Would you rap off it? M

Sell that cat to your local Chinese food Resturant, take that money you just earned and go buy new slings.

Googling around on usenet yielded the following from rec.climbing in 2000:
In reply to: I don't think it's reasonable to assume that dusting with baking soda will undo any harm the acidic cat piss might have done to his harness. Personally, I'd throw away the harness. Why take chances? It's been documented that even relatively short-term exposure to even acids as weak as urine can harm nylon climbing gear. But, if you're determined to use it again, perhaps a *soak* in a baking soda solution, followed by several thorough plain water rinses, might help. At least it will keep the acidity of the urine from continuing to weaken the nylon over time. So I'll be chucking the nylon slings and keeping the spectra ones, then. Surprised no one has suggested using the cat as a chalk bag yet. :?

You might want to be concerned with the type of detergent your g/f used on the slings.

In reply to: See if the theory that "Cats always land on their feet" holds true off of El Cap Spire........... Nah, if you want to hurt a cat the most, you have to throw it where it doesn't have enough time/distance to reach terminal velocity:
In reply to: Cats falling from higher heights do not accelerate beyond this speed, but continue to fall at terminal velocity (60 mph). As might be expected, the rate of injury in our cats was proportional to distance and speed of fall up to about 7 stories, a point just after terminal velocity is achieved. It was surprising, however, that the fracture rate decreased in cats falling >= 7 floors. To explain this, we speculate that until a cat achieves terminal velocity it experiences acceleration and reflexively extends its limbs, making them more prone to injury. After terminal velocity has been reached, however, and the vestibular system is no longer stimulated by acceleration (3), the cat might relax and orient its limbs more horizontally, much like a flying squirrel. This horizontal position allows the impact to be more evenly distributed throughout the body. Although it does not alleviate thoracic injury, it might explain the decreasing number of fracture in cats falling >7 stories.

Cat urine and slings do not mix!! I would toss evrything that was in that bag and start over. The acidity in the urine will degrade the slings, even after they have been washed. I had a cat piss on my rope bag, thank god the rope wasn't in the bag!! Sorry for the bad news :x

Damn -- how is it I always miss out on the good experiments! Conducting those test would have been a lifetime achievement. As for the cat whizz, I'd chuck the slings. Urine has been found to be more detrimental to nylon that just about anything besides battery acid. Ed

My curiosity understandably piqued, I ran by the pet store this afternoon and purchased 20 cats of various sizes and breeds then headed to the nearest skyscraper. The information above is partially correct. Allow me to explain. It is true that cats can survive falls of over seven stories. The first ten that I dropped limped away with only superficial injuries, regardless of size or fur color. Even the tenth, a tortoise-shell which I purposely flipped over the edge like a coin toss, suvived, though barely. Here's where the theory falls apart. Every one of the cats whose legs I duck taped to its little body burst upon impact like an overripe watermelon or water baloon. So there you have it, empirical evidence that no matter how many cats fall from seven stories, only about half will survive. Variables: Actually, only 19 cats were used in my experiment. The last I gave to my wife. Bastard will probably piss on my slings.

just like everybody else said. If you don't trust it, get rid of it..... as far as the pH of cat piss. You have to determine the major componet of the animal's diet because as is with humans, the range is determined by the amount of protien in the diet. more protien, more Nitrates, which are digested down into Uric Acid, or Urea. The way I remember my O-Chem like dissolves like, and it also depends on the type of nylon the maker of the sling uses. different companies are going to use different batches with different concentrations [] of Nitrogen built into the polymer chain. This will affect the availibilty of sites for the Urea to bond to and, since urea is organic it decomposes more readily than a long polymer chain you get detrioration.. beeer thirty gotta run

so if you take a big fall on sketchy gear and you piss your your pants in fear; do you replace the harness?

LMFAO *******Thanks that made me laugh so dam hard lol********* But to be serious i would say chuck them all unless you dont mind teh smell then you can save them for crap use like tieing down stuff that you move in your truck. Furniture ect.... and if you chose the later use of them i would take them lay them out and take some spray paint and paint a black stirpe or whatever color down the middle of them all to remind you not to use them.

PItt Shubert at the UIAA did some tests with nylon ropes soaked overnight in urine. The rope strength degraded by 30%, but the conclusion was that it doesn't matter except when loading over a sharp edge---the urine-soaked ropes were still strong enough to hold a UIAA drop test, which means the rope will not fail in real-life usage. I don't know the extent to which this applies to slings. Of course better safe than sorry, but if I were you I'd probably contact the manufacturer and see if they have anything to say about it.

Sorry, can't offer any useful advice, but now I feel kind of bad for sending that old guy rapelling after he pissed his pants. This dude had his own harness and was at a scout camp where I hooked him up to rapell down our tower. He's old, like a century old, and subconciously he got scared when he stepped to the edge and pissed himself. I didn't know that urine could damage nylon, oh well. He lived :roll: (partial sigh of relief/partial feeling of anger for having been pissed on) so I don't feel real bad, I guess. Hopefully he realizes that he's too old to do that anymore and doesn't use his harness again.
