The doctor at the pet hospital I took my cat to called yesterday and gave me the good news: kidneys appear not to have severe permanent damage. They still are not all better - and I have 5 weeks of antibiotic pills my cat must eat daily to prove it. However, it is a relief. She still needs a subcutaneous IV of fluids every other day - but that beats daily, believe me! She has hyperthyroidism, like a lot of cats her age. So, she has a specially prepared liquid medicine on its way to arrive her sometime today. It is chicken-flavored, to make sure she will like it.
