Cool. Many people agree with you that it's wrong to eat intelligent animals. However, the effect of intelligence on people's perceptions of moral worth is smaller for animals that people in our culture eat. For instance, most respondents in a U.K. survey said that it would be wrong to eat a tapir or fictional animal called a "trablan" if it demonstrated high levels of intelligence, but they were less likely to say it would be immoral to eat pigs if they demonstrated the same level of intelligence.
