Why does my cat have protein in her urine during cancer treatment?

You could take your cat to an internal medicine veterinary specialist for an ultrasound and/or other diagnostics to help get a definitive diagnosis. A specialist has more training then a regular veterinarian so may be able to read the ultrasound better. If you can't do that then you could try the anti-inflammatory and see if that helps. Your vet can monitor kidney function while on the anti-inflammatory. Hope she gets better soon.

Hello, & thank you for using Petco Pet Education Center, formerly Petcoach. If I am reading your question correctly, you indicate that Sapphire's urinary diet may have contributed to her developing cancer. I have never heard of this. Now, any chronic inflammation/irritation does have the potential to possibly incite a tissue to mutate to a malignant form, but again, this would be very unusual. For example, a bone cancer can developed at the site of a previous fracture in very rare instances. If your veterinarians have submitted urine to a laboratory, the sample should have come back with evidence of cancer cells. An ultrasound should also provide evidence of cancer, as well as a biopsy of the urinary bladder. If there is no evidence of cancer ( & I would be very suspicious of this in such a young cat ), then I would have no issues keeping Sapphire on a urinary diet to keep her crystalluria under control.

It is difficult to tell anything from the picture of the x-ray however, the urinalysis shows that there is a urinary tract infection which could account for the difficulty urinating. I am also concerned about the high levels of protein in the urine and a urine protein:creatinine ratio should be requested to assess kidney function. It is a good thing that the CRT is decreasing, however in order to properly evaluate kidney function the BUN levels are needed as well. Speak to your veterinarian about their suspected diagnosis/diagnoses and recommended treatments to get Tittie feeling better soon.

As she is suffering from multiple diseases, it is understandable that she is on many medications. cancer is difficult to diagnose indeed, i would recommend a specialist ultrasound, it is much cheaper than an MRI and can detect many types of cancers as well.

Thanks for using Petco Pet Education Center, formerly Petcoach! Given that the same clinical signs have come back a second time, I recommend that you have Pink re-evaluated by your veterinarian. Assuming that you perhaps were referring to a urinary tract infection, your veterinarian may choose to do a longer course of the antibiotics or proceed with a culture to treat according to the culture results. Good luck!

This does indicate kidney disease but not necessarily permanent. Cystitis can cause improper emptying of the bladder. If the bladder gets backed up, it affects the kidneys and can spread the infection there. Clearing the infection and getting the bladder emptying properly can resolve those values. You can switch him to a kidney diet and make sure he gets plenty of water. I would recheck the blood work in 1-2 weeks and see how the numbers compare. If they are worse, then you likely have kidney disease and he may benefit from IV or SQ fluids. If they improve, then it may have been a result of the cystitis and medicines

Thanks for using Petco Pet Education Center, formerly Petcoach! I definitely understand your concern. There are a few possibilities here. This could be due to an infection that is resistant to the antibiotics being given or it could be something else like stones or a tumor. I highly recommend that you consider taking Tao to his veterinarian for reevaluation. Diagnostics that should be considered at this point include a urine culture to make sure that if there is an infection, you know which antibiotic would be best to use. Other diagnostics should include abdominal imaging such as radiographs or ultrasound. Good luck and have a great day!
