My cat recently started peeing on piles of clothes. She used to only pee on bags or plastic containers on the floor but now she does it anywhere where she finds clothes. What can I do?

Question

I already cleaned with special enzyme cleaner, yet the cat can still smell her urine. Would the black light still work?

Community Answer

If there is little urine left, then yes. However, you would have to make the room pitch black to see it if you already tried cleaning it and some was left.

Question

I got a UV flashlight but it detects old paint, putty on the walls and it all looks the same as the cat urine, is there a certain kind of UV light to get?

Community Answer

No, the UV light (black light) is the kind necessary. It will detect other things along with the cat urine.

Question

Why is my older cat all of the sudden urinating in my house on my son's sweaty clothes?

Community Answer

Your cat might be responding to the scent on the sweaty clothes, so it's a good idea to keep these picked up off the floor. Sometimes older cats become incontinent, but there could also be a serious medical issue, so you should have your cat checked out by a vet. You might also try to introduce a second litter box or clean the litter box more frequently.

What are UV protection glasses?

UV protection glasses are glasses that protect you from UV light, which is quite dangerous if you look directly at it.

Question

Can't I just sniff everything to find the pee?

Community Answer

Sometimes the urine goes unnoticed until the scent vanishes, so the UV light works best. Besides, if you're dealing with potentially a lot of urine, you'll probably get tired of sniffing things.

Question

How do I find where my cat peed?

Drew Hawkins1

Community Answer

With a UV light, you can pinpoint exactly where your cat used the bathroom. For the best results, look for a handheld LED light with 9-12 bulbs. It should be rated between 365-385 nm, which stands for nanometers. A lower rating won’t be strong enough to light up the cat urine, and a higher rating is too similar to natural light to have an effect. Wait until it's dark and shut off all of the lights in the room. Then, shine your light around where you think the pee could be. When the UV light comes into contact with the urine, it should start to glow. Depending on how much urine there was, and where it is located, the stain may look like a spot, puddle, splatter, or drips.

Question

What color is urine under UV light?

Drew Hawkins1

Community Answer

Urine has a distinctive color in UV light. Wait until it's dark and turn off any lights in the room so you can more easily spot the urine. Then, shine the light around the area you suspect the urine to be and look for a glowing yellow or neon green spot. hen the UV light comes into contact with the urine, it should start to glow. Keep in mind that some cleaning products and other household materials, including wallpaper glue, may glow under a UV light, so don't panic if your whole room lights up when you turn on the UV light.

Question

What shows up under UV light?

Drew Hawkins1

Community Answer

UV light can illuminate a bunch of different things. Some cleaning products and other household materials, including wallpaper glue, may glow under a UV light. Additionally, you can use a UV light to find pet urine. Wait until night time and make the room dark. Shine the light around the area and look for a glowing yellow or neon green spot. Other substances, including some bodily fluids and tonic water, may also glow. Because so many substances glow or show up under a UV light, you'll need to use your judgment and clues like the size, shape, and location of the substance to figure out exactly what it is.
