That's interesting...my cat and her two predecessors all loved corn on the cob. When we have corn or corn on the cob cooking, my cat comes out from wherever she is and starts begging for corn before it's done cooking. She literally sits up and begs like a dog for corn. I do remember my first persian cat attacking and eating a little of the cob. She threw it up....so it might be the cob and not the corn itself that makes them sick. Since the first cat had a problem with the cob, I've only fed them kernels, which seem to be no problem for them. They literally go crazy for corn...they don't beg for anything else
