My cat has blood in urine. Is her raw diet causing crystals?

Updated On September 23rd, 2025

Pet's info: Cat | Siamese | Female | spayed | 8 months old | 8 lbs

I rescued my cat when she was 3 months old, she is now 8 and eats Darwin's raw since. About 3 weeks ago she started having troubles urinating and i saw blood in her urine. My vet did a urynalysis and came back with struvite and oxalates. Do you think is from the raw food?

Raw food has not been proven to cause urinary stones/crystals; therefore, we have to assume that she is just not metabolizing her food properly which is causing the crystals. I would get her on the recommend urinary diet your vet provided right away and keep her on that for the duration of her lifespan. If you want to test your theory at some point on the future, you surely can discuss taking her off the urinary diet and then retesting her urine to see if crystals are present again while off the raw food. But chances are, they will still be present b/c of an underyling metabolism issue. Best of luck with your pet Isabelle moving forward and I hope that you can manage her urinary issues well here moving forward. Take care.
