A belated thanks everyone.
I don't deseed the apple or pear, Rain. They never get into them that far. I have read too often that the apple seed theory is a myth so not really worried about it.
What is interesting is that Ollie has never liked banana. Yet when he was "ill" (?) I decided to see if banana might help his stomach. Surprisingly, Ollie took to the banana in a big way for a few days (ate the whole slice every morning). Now that his poops are looking so much better, he's back to not touching it again.
