My cats bun level is normal, but his creatinine is elevated to 3.0?

Question

Normal bun, elevated creatinine? Does anyone know?
Does anyone know what (besides the diagnosis of chronic renal failure, crf) could be causing my cats creatinine level to rise but his bun level to stay normal? I want to know if creatinine could signal anything else besides renal failure. Is it possible that it could be something else?

Answer 3

Mild increases in creatinine levels without increased BUN can have several causes:

1. RENAL: creatinine will rise earlier then BUN at the beginning of kidney disease

2. PRE-RENAL : when there is nothing wrong with the kidneys and the increase is caused by other problem such as:
- heart failure (decreased blood supply to the kidneys
- dehydration (not eating/drinking?, been missing?, vomiting and/or diarrhoe?)

3. Other causes:
- old blood sample (should be examined the same day)
- some antibiotics (cephalosporins)

If nr 3 can be excluded then your cat's heart function should be assessed and creatinine and BUN levels should be redone in a couple of weeks. Sometimes it happens that creatinine returns back to normal with no apparent cause.

Answer 4

Not likely to be anything other than early kidney disease, which is extremely common in older cats, and 3.0 is high but not extreme. Have the bloodwork redone (at least the BUN and creatinine) in 3-6 months to see if it's changing-the way things change over time really gives the doctor the best idea of what's going on. Kidney disease is progressive, which means you can't stop it. But there are things you can do to reduce symptoms and slow it down. The biggest 2 are to increase water intake, and feed an easily-digested food to reduce the kidney's workload (getting rid of digestive byproducts is a big part of what they do). A high-quality, canned senior cat food or a prescription diet for kidney disease are the best 2 options. Canned food has a high moisture content, so cats eating canned food take in a lot more water than cats eating dry food. Drugs aren't really an option, because almost every drug out there is excreted by the kidneys, so any medication is going to force the kidneys to work harder. There are also dietary supplements you can get from the vet that help to clear out digestive byproducts in the colon, before they make it to the bloodstream, so the kidneys don't have to work so hard. And kidney cats get dehydrated easily, so sometimes you have to give them fluids (at the vet) from time to time. Bad teeth will also put a strain on the kidneys, if the mouth is full of tartar and gingivitis, then the bacteria in the mouth can easily get into the bloodstream. Once there's bacteria in the blood, it gets filtered out by (you guessed it) the kidneys. So a good dental cleaning can help your cat's kidneys out too. Inhalant anesthetic is just about the only drug that does NOT go through the kidneys, so anesthesia is safe, although the vet needs to be pickier about what antibiotics and pain meds to use. Hope I helped and didn't confuse you too much, it's a lot to absorb.

Normal Bun Level

Answer 6

I have no clue what any of that means, but is your cat even sick? If not...why worry about it? If so...what's the vet say? Isn't that what they're for? Maybe take him to another vet and get him checked there.
