Cheryl,
My heart goes out to you for insuring that little Theo has the best care available, is comfortable and is enjoying his home. I was in the same situation with DJ for over a year after he was diagnosed with significant glourmerii damage in his kidneys and a liver shunt closed off at 6 1/2 yrs. The glourmerii/protein loss was too much for his little body to take anymore and we laid him to rest 1/23/08 after only having loved him for a year and a half.

Love him like there is no tomorrow. Take plenty of pictures/videos like Mike does to preserve those precious memories.
Bob
