Oh, yeah. I posted a few weeks ago about my cat. She is dying. Renal insufficiency. The vet's told me yesterday that her blood indicates that she is much worse than she was. You would never know it from her behavior. She is playful (for a 15 year old) affectionate, eating and drinking, and just acting normally, allowing us to give her subQ injections with minimal fuss.
She was my buddy while dealing with all the nonsense with SAfWH. My rock. She never leaves my side.
I'll miss her. I'm glad you have a furbaby to give you comfort.
