In the case of kidney disease that is an especially dangerous attitude as by the time tests can confirm CRF it is already advanced. 

Good point. agree.gif

Thank you for sharing your thoughts. There is no "big deal" being made of "this issue". I want to educate myself, and understand certain things. It's as simple as that. smile.gif

I wish to gather information, knowledge and understanding. I prefer to know and understand as much as possible about my cats' health. It's important to me to be able to discuss things with my vet, sharing knowledge and learning, to the benefit of my cats' health. The more I know, the less I worry, and the better the care my cats get.

Of course! You are to be commended for learning as much as you can about how to keep your kitties as healthy as possible.

 

I can't agree that a big deal isn't being made of this issue. This thread is proof of that. You are obviously still concerned that the higher BUN, creatinine and hematocrit values of a cat fed a high protein diet might cause some complication with your vet in diagnosing your cats. I'm trying to explain why that fact is causing you, and possibly others, needless worry.

 

I don't feel I have made my point clear. The fact has been brought up that cats fed a high protein diet have higher BUN, creatinine and hematocrit values in their blood workups. As a result of that fact people, such as you, have gotten the idea that they need to "warn" their vets of that fact so that the vet doesn't made a erroneous diagnosis of a kidney problem based on the higher values. That is an unfounded concern.

 

As the study Laurie posted indicated a cat fed a high protein diet may have slightly higher BUN, creatinine and hematocrit values that that they should still be within the normal range. The blood work of any cat, regardless of that it is fed, can come up with values at the upper end of the ranges. That is why what is "normal" is a range and not a specific value. Also, as has been pointed out in this thread, the BUN, creatinine and hematocrit values being outside of the normal range will not cause a vet to diagnosis a kidney problem. They are just clues that further testing may be needed. And no vet should look at those high values and say "Well, the cat is fed a high protein diet so I'll just assume the kidneys are OK" without doing further testing.

 

Bottom line, if a cats blood work reveals those values outside of the normal ranges, a kidney problem should still be considered a possibility whether the cat is fed a high protein diet or not. In other words, that the cat is fed a high protein diet and that such a diet can result in slightly higher BUN, creatinine and hematcrit values simply isn't relevant.

 

OK, I'll stop pounding on this topic now. I'm sure everyone has had enough of it. From me anyway. laughing02.gif

 

I hope you have an uneventful visit with your vet!

Mazy had her check up today. Turns out vet is already familiar with the possibility of a higher BUN in raw fed cats. Managed to get her there with a full bladder so they got the urine too.

Gosh I hate putting her through it, especially the full bladder part. I used evil trickery. Mazy and I have a morning routine. First thing in the morning, after her pre-meal serving, either she tells me, or I tell her it's time to go down to the litter boxes. If she tells me, and I don't act, she waits. This is because she knows I want to see her pee, and some times inexplicably poke a little white paper stick under her when she does.

I was counting heavily on that routine this morning. Instead of the pre-meal I gave her a pepcid with a tiny bit of freeze dried chicken breast (she was fasting because of blood work but I figured that would be okay), then ignored her when she did the sideways "take me to the litter box" dance. When I did finally head down she ran down in a big hurry, she really had to go! Before she could jump in the litter box I snatched her and poked her into the carrier. I didn't feel good about it, but I had to get her there with a full bladder.

Lab results on Friday.

i said I would update this particular thread when we got new information on Callie, so this is it:

 

With her latest blood test and Urine Specific Gravity Test, the conclusion is that she DOES have early signs of kidney disease frown.gif.  Please take note that some of  her values were OUTSIDE the norm.  Not just high, but higher than norm, both for BUN and Creatinine.  Here is what her trend has been:

 

                                        8/2012          4/2013                 7/2013

 

BUN                                  34                   49                     44

Crea                                  2.8                  3.1                   3.3

Bun/Creat Ratio                12%                16%                 13%

USG Results                 perfect!              N/A                 1.029 (considered in the normal range, but indicates an issue with above numbers frown.gif)

 

BUT, for those who are feeding raw, or thinking about it, I want to preface by saying Callie was on kibble for 12 years prior to starting a raw diet,  so I honestly think if we had not changed her diet when we did, she would be a LOT worse.  That's just my opinion, granted, but I'm gonna go with.  And hopefully now that she is on a really good diet (not raw now since she's on strike, but at least a good high protein, high fat, low carb, low phosphorus canned regimen), she will not get any worse.  cross.gif  She must be feeling pretty good, because she is actually out and about more than usual, and even playing more than she has in the past year or so biggrin.gif

Yes, I can see the trend and cause for concern and paying attention there with the steady climb in crea and bun.. Mazy's went up from 1.8 June 2012 to 2.0 June 2013. Last year at the time of her blood work she wasn't on raw yet but had been on canned for the previous 6 months, prior to that she had been on Hills c/d kibble for 6 1/2 years, and her crea had 1.1 (2009) or 1.2 (2010 and 2011)

This was Jennie's first blood work and hers was 2.2.

The lab results still indicate that 2.4 is high normal but my vet tells me the veterinary field is looking at 1.8 as the new high normal. However she does feel that Mazy's and Jennie's numbers reflect the high protein diet rather than any concern over their kidneys as all other related numbers are normal.
