Our 18 month old female cat (kitten) was hospitalized with renal
failure 17 days ago.  We suspect lily toxic poisoning but we are not
positive, however, her symptoms appeared 24-hours after a lily plant
arrived and she had pollen all over her face.  She was fine before
this.

Her BUN and Creatinine where 150 and 10.4 respectively when she was
hospitalized.  All other blood values where in the normal range.  She
was not anemic which the internist said would go more with chronic or
congenital kidney failure.

She was in ICU for 12 days ( a long time) with IV fluids.  She also had
an esophageal feeding tube and a urine catheter to measure urine
output.  Her urine output started a 2ml/kg/hr and went up to 10ml/kg/hr
which was encouraging according her internist.  When she was discharged
after 12 days her BUN and Creatinine fell to 37 and 3.0, respectively.
She was also given an ultrasound that showed normal looking kidneys.
Unfortunately, during her stay she developed a urinary infection
(likely cause was the catheter) that is being treated with Baytril.

We took her home a few days ago and are administering fluids and food
supplements via her esophageal tube.  She is not very active and does
not want to eat much on her own.

Does anyone out there have any experience in this area that they can
share?   If she is doing better shouldn't she be more active and
interested in food?  I understand that we are supplementing her normal
eating with the esophageal tube but even after 8-hours between feeding
you would think she would have more interest in food.
