anybody feed Hill's Prescription Diet z/d? and why can't I search the forum anymore?

post #1 of 5
Thread Starter 
my cat Kirby has been having intermittent blood and/or mucus in his stool for many months. we first took him to the vet, who gave us an IVD Neutral food to try, but he didn't want to eat it. we then switched on our own to the Natural Balance Venison and Green Pea, but the blood would still pop up here and there. so back to the Vet. no positive for parasites, so seems to still be food. he did prescribe a medication that we used for 5 days (not sure the name here at work), and we've now been slowly introducing the Prescription Diet Feline z/d Low Allergen into his bowl. this food has "Hydrolyzed Protein" that, Hill's claims, eliminates animal intact proteins and significantly reduces the possibility of an adverse reaction to food.

unfortunately, the ingredient list doesn't appear to be so great, given what I've learned here and elsewhere... rice, BHA, in the dry, and corn starch in the wet... (below are the full ingredient listings). but if going onto this food alone will help the current issues, i suppose those things are of less concern...

just as way of background/additional info, the blood/mucus seems to be an isolated issue. he doesn't appear to have any less energy, he ate the same amount, if not more, of the Venison & Green Pea food, etc. his overall behavior hasn't seemed to change at all.

thanks for any advise/insights,

No experiences with z/d, but as for Natural Balance, I've I had the same problem with Miko. He was eating Natural Balance's Ultra Formula and suddenly developed a UTI. After his surgeries, the vet said it was okay to feed him canned as long as it was high quality since he HATED the c/d canned formula. We fed him the same NB formula and he still developed crystals in his urine. After many urine tests, medications and daily check-ups, Miko is banned from eating Natural Balance. He's been doing good on Merrick and California Natural, with a little bit of Science Diet C/D. I can't help but wonder if anyone else has had a similar problem with Natural Balance...

P.S. I never liked the ingredients in SD, but at this point, I have no choice. It's the only thing that keeps Miko's urine "stable".

Z/D is a wonderful creation//// I dont like the ingrediants but how they are formed is key...

To be perfectly blunt, the stuff scares me.

First of all, there's the issue of RICE as the primary protein source in the dry food! To me that is just crazy.

Second, I have to wonder about how wonderful it is to eliminate "intact animal proteins". If the food is processed so much that the immune system cannot recognize it, I have a very hard time believing that bioavailability is not also significantly compromised.

All in all, I would't go near it. All living things need real food, not food that has been processed literally beyond recognition.

A drop of blood at the end of a bowel movement does not necessarily mean anything is abnormal. Mucus does indicate something is up. If you have eliminated the mucus, then you've probably done what you needed to do.

Hi, the forums are undergoing an upgrade, and that is why the search function is currently disabled. Not to worry, it will be back soonish

My Joshua (RB) was on Hills Z/D for several years...it was his last chance, and it extended his life for those years. I didn't and do not care what the ingredients were, it worked. I have always advised that when it comes to a prescription food, unless you can find a food that is formulated comparably but with better quality ingredients, you should use it.

When I have found comparable foods, I still always run it by my vet to get their opinion, and to let them know what I want to do.
