Mary, I'm so sorry to hear that she hasn't shown any signs of improvement. Maybe she peed in the sink because she's just too tired to make it to the litter box. At least she did it there instead of on your carpet or bed. I sure hope that she'll get some energy back and start feeling better.

Her hiding reminds me so much of when my RB Pepper was so sick. He hid back in my room for so long that my cats Storm and Sunny just got used to not having him around. When I would try to force feed him and medicate him he would let out big sigh. I knew that he had enough and wasn't ever going to get better. I'm sure that Puddy will let you know when's she's had enough. I'll continue to keep her in my thoughts and prayers. Please take care of yourself too. (((HUGS)))
