Thanks for the kind words and thoughts about my dad. He is out of hospital now and feels a bit better even though his problems could reoccur (he's got hear problems). Being 81 does not help. On a brighter note, one of my cats Maya is keeping his spirits up (my dad is staying with me), she goes and checks on him, and, even though she is not a lap cat, she will sleep on his feet. Since she did the same when my mother is sick I'm thinking of changing her name to Florence Nightingale! Nothing better than a little in-house pet therapy.
