Thank you all so much. I do have Giles in a separate enclosed area ... complete with a large kitty condo and a built- in perch. He doesn't seem to be troubled by my cats ... everytime I go in there, he is lying comfortably on top of the condo. It's totally me that freaks him out. He did the same thing this morning, and finally when I managed to corner him on top of the condo, I gave him a tuna treat "peace offering" ... and he gladly gobbled it up.
I have been making eye contact with him (a mistake, apparently) but I do blink my eyes slowly at him, as I did know that was a loving glace to cats. Uugh.... I guess I will either blink constantly (hehe) or never look at him.


Giles is approximately 5 months old ... so yes, he has had a long time in "the wild".

Thanks again for all of your advice, support and concern.
