This Is How To Get Cat Pee Out Of Yarn Successfully

Getting cat pee out of yarn does require some work. Here are two different scenarios for the problem of the cat peeing on yarn.

Firstly, the cat may have peed on the knitting that is a WIP (Work In Progress). You may be halfway through a knitting project and when you come back to the project, whether a few hours later or weeks later, there is a tell-tale cat urine smell and your heart sinks. The cat has peed on the yarn.

Secondly, the cat may pee on the yarn in your stash. A “stash” (in the knitting world), is yarn or wool that is waiting to be knitted. No stash shaming here, but stashes can get on the largish side, so you get the idea. Cats peeing on yarn in the stash is a common problem

Yarn is a comfy place for cats to hang out. If the yarn is not packaged or in a container, the cat may pee on the yarn. Yarn that is stashed and waiting to be knitted, may be still in a hank or already wound into balls or the yarn may be in a yarn bowl.

The yarn may already be knitted and be a completed or semi completed garment, for example, a sweater.

The term ‘yarn’ is commonly used in the USA, however, in other countries, such as the UK or Australia, ‘yarn’ usually refers to wool.

A store selling wool in Australia would be a wool shop, and in the US, a yarn store. Just to get that out of the way. I will use the terminology, ‘yarn’ here. As we live in an increasingly connected world the term yarn is being more commonly used in the UK and Australia.

The yarn/Pee problems

I have compiled a comprehensive list of all possible solutions to get cat pee out of yarn.

These solutions to get cat pee out of yarn are from other knitters who have had this problem.

The solutions are the solutions that worked for other knitter.

As well as describing the process of removing the cat urine, I have, where possible, included comments about the actual results.

Some of these methods to remove cat pee from yarn, overlap. Take the information here and apply to your situation.

How To Get Cat Pee Out of Yarn

Problem 1: My cat peed on my WIP. What should I do now?

Solution 1

First of all, put all the stitches on a safety line so that you can temporarily remove the knitting from the needles. You might be cursing kitty under your breath at this stage.

A safety line can just be a length of spare yarn, that is threaded through all of the stiches so that the needle can then be removed. Next, the safety line yarn is tied securely.

The other option to using yarn is to use cord as shown in the image below. I love the cord and am a recent devotee, having just used yarn as a safety line previously.

Next, hand-wash the yarn in an enzymatic cleaner.

Then wash in a wool wash to make it all lovely and soft. Remove excess water and let the yarn air dry. When the yarn/sweater etc is dry, put it all back on the needles and keep knitting.

Solution 2

Someone else recommends Furry Freshness for this problem. Furry Freshness is 100% natural, non-toxic, and has no fragrance or enzymes.

Furry Freshness works by triggering pet accidents to breakdown and dissolve into oxygen & water. It also triggers pets stains to completely breakdown.

Another recommendation for this cat peeing on yarn problem, was to put the knitting out in the sun when their cat peed on their knitting. This may work for lightly soiled items.

I would definitely wash the knitting first.

Solution 4

Soak the knitting, using a wool wash while it’s still on the needles. This knitter remarks that it’s a little odd to do, but they have done that with projects the dog peed on.

Solution 5

Try this method to remove the pee, before you discard the WIP. Mix 16 oz of hydrogen peroxide hydrogen peroxide 3% solution, 1 tsp Dawn, 1 tbsp baking soda, and mix together. Put this mixture on the affected area. Let it air dry completely and brush away the excess powder.

This is an excellent remover for cat urine on yarn (according to the contributor).

Problem 2: My knitting bag held a current project and a few skeins of yarn. The cat peed in the bag!

Solution 1

Last week, I had to de-pee 4 skeins. I made them into hanks and then soaked them in enzyme detergent for a day.

Next, the hanks were carefully washed with wool wash, hung to dry, then they were balled into cakes.

It wasn’t as hard as it sounds as long as you’ve used hanks before and know how they are tied to prevent tangles.

Note: Make sure the hanks are tied, otherwise an almighty tangle could be the result. This is a super quick video, approx 2 mins that shows how to tie a hank.

There is another video further down the page that explains how to make a hank, with no special equipment needed.

Solution 2

This is for after you have solved the yarn pee problem and to hopefully stop any further cat urine incidents.

Have you tried Feliway spray for cats?

It’s a pheromone spray and calms cats that are stressed. It mimics the cat’s natural facial pheromones (when your cat is rubbing the side of his face on furniture, your shoes etc).

Solution 3

Look for a product called Nok-Out Odor Remover (shown below), Pet Deodorizer, and Cleaning Spray. It is an enzyme cleaner that is safe for even the most delicate of fibers.

Solution 4

I used an enzymatic cleaner on two machine-made wool rugs. It got the smell out and the colors ran on only one. It happened to be the one with a lot of red in it.

The color ran into the fringe that is now pink instead of cream colored. I used Nature’s Miracle as my cleaner.

Problem 3: I stored a baby blanket in my yarn bin. The cat peed in my yarn bin and on the blanket. How can I get cat pee smell out?

Solution 1

The best thing I know for getting cat pee out of fabric, is called Odor Mute.

Solution 2

There is a product with enzymes that digests urine called Nature’s Miracle. I’ve never used it on yarn, but I have 3 dogs and it has saved our carpet many times. Maybe spot test it on some scrap yarn?

Solution 3

I would use Nature’s Miracle. Soak it well. Rinse and soak it again.

Note: Nature’s Miracle has been mentioned multiple times. To be fair, I don’t know if this is just because it is a well-known brand or because it works so well – maybe a bit of both.

Nature’s Miracle is an enzymatic cleaner that is specific to pet urine stains. Get if from a pet store or online.

Solution 4

This is a ‘Thinking Out Of The Box’ solution. Hunters use a laundry detergent that is scent free, to wash their clothes (and a body wash) to help them go undetected when hunting.

These products also work to get rid of stains.

I am not a hunter, but here is the information about both of these products. Some of you may already know about these or similar products. Both are listed as safe to use on merino wool.
