high urinary pH - advice needed
Hey y'all,
Well Levi has been on the Hill's S/D for 5 weeks or so now. He had his urine checked on Friday, and there was no evidence of crystals, but his pH was high again, at 7.65. There were also white blood cells, but not enough to suggest an active infection (and his temperature was normal). The vet sent urine off to a lab to double-check. He called me today to tell me they confirmed his findings. He's a bit perplexed. S/D is supposed to bring the pH down, but clearly it's not working. My vet is going to keep Levi on the S/D for another 3 weeks and recheck. He hasn't been getting ANY other food or treats. What else might be going on? Thanks! |

How much time elapsed between his last meal and testing the urine sample? Feeding can definitely affect urine pH. Feeding releases bicarbonate which results in a postprandial alkaline tide that causes transient alkalinization of urine. Phil |

Is there a possible correlation? THANK YOU. |

Is there a possible correlation? THANK YOU. Just a --possibly stupid-- question, but what kind of cats do you have? Mine is quite old by now, and has a kidney problem, and has eating problems, but still I found two remainders of mice around the house, and I have good reasons to think he has eaten them... I have no idea when the latest meal of our cat was. In fact, when I put his food tray outside the house (he won't eat inside, for reasons only known to him ;-) ), I can only see that he eats some of it, and next I see birds feeding from it... so he eats some, but not all. So, just wondering, how do you know when the latest meal of your cat was? Do you always keep him inside? Does he accept that? When we moved, about 5 years ago, we could keep him in for about a week... Well, cats are miracles on four feet anyway, but one cannot stop wondering ;-) |

Do you think the timing of his last meal could have effected his urinary pH? |

Try these: http://www.vet.uga.edu/sams/courses/...icCystitis.pdf http://jn.nutrition.org/cgi/reprint/...uppl/2652S.pdf Do you think the timing of his last meal could have effected his urinary pH? Yes. Foodstuffs also exert major effects on urine pH. Sulfur-containing amino acids, phospholipids, and phosphoproteins which are found in higher quantities in meats acidify the urine, whereas plant materials alkalinize it.. You might want to pick up a Hanna ph Checker 1 and a Breeze litterbox so you can monitor his urine pH whenever he pees and plot the urine pH throughout the day. Just replace the absorbent pad in the Breeze with a baking or cookie pan- makes getting urine samples a "breeze"- (pun intended). Phil |

You're a constant source of invaluable help on this ng, and much appreciated. I just re-read your first post and realized I overlooked that he's been eating s/d! duh. His urine shouldn't have been alkaline 7 hours after eating s/d. Does he get very stressed out by trips to the vet? If so, you might want to check his urine pH at home- or at least collect the sample at home and run it over to your vet to check. Cats that are very stressed-out can develop stress-induced respiratory alkalosis that can certainly alkalinize his urine. |
