@firefly,
Firefly, Blue Eyes did not come home with me today it will instead be late tomorrow.
The vet recommended that I leave him with them for one more night/day to make sure he is as stable as he seems.
The vet stated that he did not get a lot of sleep the night before in keeping a watch on a cat that could had gone either way.
Then he said in some amazement, pointing to a large almost empty can of high calories cat food in the cage “Your cat just ate the bulk of this whole can”.
Looking at the can I saw that what had not been eaten was in the bottom corners of the can so with my fingers I move the remains to the center and Blue Eyes then finish up his meal.
This from a cat that was almost unconscious and so far gone his body was shutting down not even maintaining his core body temperature when I brought him in.
Cats are amazing in many ways.
Thanks you all for the emotional support you had granted me on this thread.
