Why is there no "con" in front of "cá"?
Because when you're talking about something in general you can omit the classifier/counting word.
So would "va ga" be "and chicken" in this sense?
I put con cá and it was marked incorrect. Bit harsh
When talking about eating animals you should use "thịt" (meat) and not "con" if you need a classifier.
co ay an com ca
