Thanks for all the advice, but he passed sunday (5/31). I think the pet store waited too long or he had something serious from birth.
He never perked up even with increased temp and light. By Saturday night he wouldn't move at all on his own, and didn't really open his eyes even when touched or hearing noises.
So sorry he didn't make it- I was afraid of that, but at least you tried.
Rudeness is the weak man's imitation of strength. Eric Hoffer(1902 - 1983)
