Hi folks,
Haven't been here in quite some time. My civvie Hobbes has been diagnosed recently with early stage CRF. My vet recommended looking into using a supplement called RenAvast which she says they have had very good results with in clinical studies. It is a compound of naturally occurring amino acids and peptides giving as a supplement in a sprinkle capsule. Studies show that it may have some beneficial results in improving kidney function and potentially halting the progression of CRF.

Was wondering if anyone here has had any experience with it.

BTW... for those of you who remember us... Flamie is doing wonderfully! OTJ since June 2008 and going strong! He is my happy little goofball!

Hope you and all of your extra sweet furkids are doing well!! xoxo
 
You may find it helpful to review the Cat Info section on urinary tract health

While it may be true that some cats with renal disease have lower levels of certain amino acids, this may reflect inappetance (disinterest in eating) and feeding a diet too low in quality protein. Supplements aren't what is needed; a decent quality diet is just as likely to do what is needed, without the extra expense.

A list of food suitable for diabetic cats with renal disease is posted here in Health frequently.
 
Hi Larry,
Thanks for the pointer to that web site and article on RenAvast. Will speak to my vet again regarding whether this is the way to go and why she is recommending it.

Hi BJM,
Thanks to you too. I am very familiar with Dr. Lisa's web site and pretty much all of the info there. Thanks to Flame's FD diagnosis back in 2008 and thanks to the good people here at FDMB, my cats have been fed a high quality, species appropriate diet since I came here and learned all about feline nutrition. They had always gotten canned food along with dry, but wish I'd known about the dangers of dry way before that time. I have been making my own raw food as well for almost 5 years now.
The one thing Hobbes is NOT, is inappetant. He eats very well, thank goodness.

I initially thought he might be diabetic, he has all the classic symptoms. Weight loss despite having a great appetite, drinking a bit more water, urinating more. But blood/urine and home BG testing say he is not diabetic. Have had his thyroid checked twice now and he is not hyperthyroid either. Vet did say that kidney issues can sometimes cause weight loss. This is all very new, so am learning... just like I did with Feline Diabetes.

Thanks again for your responses.
 
Has your vet done labs to confirm kidney function and thyroid levels? High thyroid levels are very common in cats and also cause huge appetite/weight loss so is good one to check given his symptoms. Thyroid levels is usually a test you have to add on so it may not have been included even if your vet did labs recently go monitor his CRF
 
Hi Lisa,
Yes, just had complete labs re-run this past week to check kidney function and thyroid again. Am monitoring every 2 - 3 months to check for any changes. Thyroid levels are within normal ranges.

Thanks!
 
Cats can get diabetes insipidus, a different type of diabetes. Frequent urination is a symptom. Something to discuss with the vet.

From the Merck Veterinary Manual online

"Nephrogenic diabetes insipidus is a physiologic condition in which the kidneys fail to concentrate urine despite adequate amounts of antidiuretic hormone (ADH). Central, or pituitary-dependent, diabetes insipidus develops when there is a lack of ADH production. Animals with central diabetes insipidus can be given desmopressin acetate. The nasal spray formulation can be used, with 1-4 drops administered into the conjunctival sac sid-bid. Alternatively, the parenteral form can be given at 0.5-2 µg, SC, sid-bid. Thiazide diuretics may reduce polyuria by 30-50% in animals with nephrogenic or central diabetes insipidus. Inhibition of sodium resorption in the ascending loop of Henle leads to decreased total body sodium and contraction of the extracellular fluid volume. The net effect is to increase sodium and water resorption in the proximal renal tubule. Chlorothiazide is given at 20-40 mg/kg, PO, bid."
 
I havent heard of Renavast but I do have a cat with diabetes and CKD - I use a supplement called Azodyl. Its had enough annecdotal evidence of being beneficial in treating kidney disease that the University of Colorado is doing a double blind study on it. A couple of things - its a little spendy ($35.00 a bottle with 60 capsules) and it needs to be refrigerated (if you buy it from 1-800-Pet-Meds you have to pay more for overnight shipping). That being said its kept my cats kidney disease stable for well over a year and half - her creatnine went from 4.8 to 2.9 after using Azodyl. Another thing that will help extend your cats life is subq fluids. These help keep your cat from becoming dehydrated and keep the kidneys flushed out. There is a website called Tanya's CRF site that is just as awesome as this one for information on treatment of kidney disease. Oh the other thing is to feed canned food that is lower in phosphorus - I cross checked Tanya's list with Janet & Binky's to find food that fit both the lower carb and lower phosphorus requirements.

I found this site really helpful (Tanya's crf). Little Boy is in hospital with a stone in his ureter (sp?) - from his kidney. The kidney is being damaged by the blockage. They are hoping to flush the stone out but it seems that only 10% of stones are removed this way. We are not as advanced in treating blockages in Australia as in the US. It's all looking a bit grim. :sad: But it really helps to come on to FDMB and run thru a few health messages to find such a brilliant site. What a marvellous woman to put all this info on the net for us moggy folk.
