private void mealButton_Click(object sender, EventArgs e)
        {
            int i = mealComboBox.SelectedIndex;
            MealLabel.Text =  animalManager.AnimalList[i].eat;
        }


needs to be

private void mealButton_Click(object sender, EventArgs e)
        {
            int i = mealComboBox.SelectedIndex;
            MealLabel.Text =  animalManager.AnimalList[i].eat();
        }


Parentheses after the eat - it's a method call.

Actually that's not quite right either - I'm not quite sure what you're trying to achieve but the following:
MealLabel.Text =  animalManager.AnimalList[i].eat( "Some food" );

Would work as an example. Something seems confused in the code though

Thx. Been sitting to long today....so I got a bit blind. Of course you are right. I didnt see I should have something in and I forgot the ( ). Here is a working function: :-)

private void mealButton_Click(object sender, EventArgs e)
        {
            Int32 selected = AnimalDataGridView.CurrentRow.Index;
            MealLabel.Text = animalManager.AnimalList[selected].eat(mealComboBox.SelectedItem.ToString());
        }
