@Wendy&Neko I'm going to copy and paste the entire email that I just got from my vet. Please give me your thoughts.
Hi Darcy,
If there truly are ketones in Jonesy’s urine, that would be cause for concern. Persistent ketonuria is due to an upset in energy metabolism, when the body is using fat stores rather than glucose for energy production. It can therefore be seen in unregulated diabetes, or from malnutrition or starvation.
Also, I say “truly” because ketones strips can be misread – for example, diabetic cats are prone to getting urinary tract infections due to the high glucose levels in their urine. If this is causing red blood cells or other impurities to come out in the urine, it could falsely change the colour on the test strip.
If Jonesy still has ketones in his urine that would make me think that his diabetes is not well regulated. If Jonesy is showing signs of increased thirst and urination, this would be even more likely. There can be many reasons for this. His insulin dose may not be adequate, he may be resistant to insulin, he may have another infection occurring, he may have pancreatitis (the pancreas is responsible for producing insulin in the body, pancreatitis means it’s inflamed), or he may have another disease occurring that we are unaware of that is playing a role in insulin regulation, such as another endocrine disorder.
Therefore, we would need a full urinalysis and complete bloodwork, or at the very least an accurate blood glucose reading, to know what may be happening. Abdominal imaging is often a good idea as well, so we can visualize the pancreas and urinary tract to check for any abnormalities that may be causing him to not regulate.
For these reasons, we don’t recommend testing ketones regularly in diabetic cats as it does not tell us much about what is going on, but gives us more questions than answers. We do recommend performing blood glucose curves (checking blood glucose immediately before an insulin injection and then every 2 hours until the next injection) to more accurately judge whether a cat is well controlled. We do these every 6 months or so in “well” diabetics, and more often in diabetics showing signs of increased urination and drinking, or a couple weeks after changing an insulin dose.
The last blood glucose curve I see from Jonesy is an email from January 7th. At that time the doctor recommended increasing the dose to 2 units twice a day, and repeating a curve in 3 - 4 weeks. Was a repeat curve done then? Vanessa mentioned that a reading came back low, and so you brought the dose down to 1.5 units twice a day, was a curve done at this time or since this change?
In summary, at the very least, I need a blood glucose curve to be done on Jonesy so I can get an idea of what exactly may be going on. A full urinalysis would also be a good idea.
Let us know if you have further questions,
Dr. Melissa Cavanagh
