My cat has shiny urine crystals. Does he need an emergency vet now?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Male | neutered | 7 years and 4 months old | 15.4 lbs

I believe my cat has crystals in his urine. I was cleaning out the litter box and the piles looked shiny. Then in some of the urine there were small pieces that looked like hair with crystals in it. I know these can lead to blockages and am very worried about that happening since he’s a male. Does he need to go to the emergency vet?

As long as he is urinating within his usual frequency and volume and does not have any discomfort or blood with the urine I would not be immediately concerned with regards to an emergency visit unless anything changes. I would recommend submitting a urine sample to your vets office for analysis - you can use special urine collection litter in order to collect this from his litter tray. Your vet team can then assess concentration, pH and presence of microscopic crystals which can help to evaluate urinary health. A wet diet, or a dry diet specifically formulated to reduce crystal formation can be used to lower risk also.
