      Ok, this is good. I just want to throw out a teeny reminder that not all
      infection shows up all the time...and it's possible to have a low-grade smoldering
      infection that's not detected. I'm not saying Hobo has one. Only that it's
      possible.

      > --urine did have increased number of red cells
      >
      How about blood? It's possible to have blood/RBC in urine from some type of
      inflammation...without bacteria. And if Hobo does have sterile
      inflammation/hematuria, there are some gentle remedies that can help.

      I'm assuming they did a special test for the microalbumin (as opposed to the
      dipstick for protein)?? Are they also going to check blood pressure? The test
      for microalbumin detects 1-30 mg/dL. The usual ref. range for BUN is 14-36
      mg/dL and creatinine 0.6-2.4 mg/dL (altho some labs consider the upper range
      1.8).

      It would be helpful to get results also for phosphorus, potassium, sodium,
      hematocrit/PCV, and urine specific gravity.

      All this sounds good except the funny-looking thing.

      No, this really isn't a good idea. This is outmoded thinking...that should
      never have been applied to cats to start with. Without going into a long
      explanation, the goal is to keep an eye on the amt of phosphorus, while providing the
      highest amt of high-quality protein possible.

      This phosphorus content on this is about 1.18% (dry matter). I think 1% is a
      reasonable amt...and this isn't too far from it.

      I don't know either. I think it's unlikely...but I certainly couldn't swear
      to that.

      I'd want to know the blood/urine results mentioned above. And also ask if he
      thinks a blood pressure check is needed.

      Yes, Lisa!! Bingo. Actually, his whole body needs the protein, b/c Hobo's
      whole body evolved to get energy and nutrients from animal protein.

      same principles apply to cats):

      I hear you about this...it isn't the most fun way to spend 4 min with your
      cat. But it's not dreadful, either, and hydration is so important for overall
      comfort and health. And Hobo may not need fluids right now. You can also keep
      him hydrated by adding some extra water to the food or encouraging him to drink
      (eg if he likes a fountain)...and some caregivers also give water by oral
      syringe instead of subQ. When the time comes, you can get help with the fluids,
      too (if you need it). // Rosemary
