Thanks Saerra, Kuroneko, and MCsc.
Today they actually had chicken that was cooked in the slow cooker. I cut it up very finely, with scissors and put it on a paper plate for the mama. Waffles (the fat cream colored one) surprised me by walking over and sitting next to mom and actually eating it.
I have been leaving dry food out all along, so I suspect they have been nibbling at that as BeMi suggested they might. The little grey one (Agador) didn't want anything to do with eating, though. She was too busy playing. She's a lot smaller than he is, I suspect she is the "runt" of the litter. So I was thinking she just isn't ready yet. Still it was encouraging to see one of them eat.
The thing is, as much as I hate to admit it, I cannot keep them both. My oldest daughter has found a home for Waffles. Really, just typing that makes me get tears in my eyes, because I love them both. She told me the people that want him would like him to come home in a couple of weeks if possible, so it is good that he is starting to eat. I would never let him go before he was weaned though, and I was firm with my daughter about that point. I suggested they take the mean ol mama cat instead.
(You may or may not know that she attacked me on Christmas day, to the point of leaving scars.)
Anyway, thanks for the advice. So far one seems to be trying out real food, the other is still uninterested.
