We had to take her to the vet yesterday with an emergency appointment. She started throwing up (yuk) two days ago and by yesterday morning was quite ill.
Her vet found she had a bad "infiltration" of fleas (who knew under all that fur?), which she brought with her from her original home that had many cats. They ran lots of tests but nothing showed up that would cause these symptoms.
They sent her home and said to see if the flea treatment helps her to be able to keep down food. So far, she hasn't been able to eat or drink for over two days now and she continues to be lethargic.
We certainly do not want to lose this one to whom we have become so attached. We will update you tomorrow.
NOTE: No, we did not have X-rays taken as they are quite expensive... just lots of blood tests. Which cost enough, yikes! Should they be necessary, we'll do it. The doctor said to see if she gets better first (they were Sasha and Storm's vets so they know my husband is on Disability).
