My cat tends to puke more often if i give him any more than 1/2-3/4 cup of dry food at a time. (also all food, not digested).
Try only giving 1/2 cup in the morning and 1/2 cup in the evening, see if that helps. Also back off the treats, if you give any, this also seemed to trigger my kitty's vomitting episodes.
