Thank you for your wishes!
With today's trip to the vet's, an x-ray and blood test later we learned she had kidney failure.
Even though I asked 5 different times if there was anything else we could do,
it seems that kittens can't recover from this no matter what you do.
It was so wonderful to have Dango for the time that we did.
I am very thankful that we were to ones who adopted her and got the oppurtunity to spoil the heck out of her during the short time she had.
