Could my cat have had her kidneys fail due to stress?
Our 12 year spayed female cat was diagnosed with stage 1ish (possibly early stage 2) CKD in May of this year. Her creatinine was 173 umol/L. We started her on renal support wet food and she was doing well.
About five days ago, she started throwing up a few times and barely eating. We took her in two nights ago and her creatinine was 1080 umol/L and BUN was >49.98 umol/L. The vets were shocked and said she was in late-stage kidney failure. Back in May, her creatinine was only 175 umol/L.
The plan was to keep her hospitalized with IV fluids and daily blood work. We were hoping she would stabilize and we could take her home with daily SubQ fluids.
24 hours later, they performed blood work again and said the creatinine was still increasing and her potassium kept increasing as well, meaning the kidneys could not filter it out. They were worried about her heart with the potassium increasing. However, she did eat a couple bites and was still peeing. They told me she is suffering and don’t believe she will get better. We decided about 36 hours into her hospitalization to put her to sleep.
BACKSTORY:
This all started last Friday, about a week ago. My sister brought over two 8 month old cats for about 5 hours for a ”play date”. My cat has met these two cats twice before. They would stress her out whenever they’d get too close and she would hiss at them. She spent most of those five hours on her cat tree. After they left, she ate a late dinner of wet food around 11 at night. Sometime in the early morning, she threw up all the food. Every since throwing up, she kept losing her appetite more and more until her eventual hospitalization.
Could this five hour visit have been the trigger for her kidneys to fail? Maybe if she didn’t drink that day from stress due to the kittens? I just don’t get how this happened and the vets have no idea. Her blood work and urinalysis did not show any signs of infection.
Any advice is appreciated.
