Do you use the imported counter? Do you have the code so that an animal will eat another class? If you can answer both questions with "yes", then copy the following line to the place where an animal eats another class: 
getWorld().getObjects(Counter.class).get(0).add(-1);

then i will have to create a "add" method right?

I think there is already an 'add' method in the imported Counter class. If you created the counter yourself, then yes, you have to create such a method.

((Counter)getWorld().getObjects(Counter.class).get(0)).add(-1);
Maybe this will work?

No offense, but typing in ´Greenfoot counter´ in google should give you plenty examples and explanations...

"it does not work"... What is the error message? Can you post the related code?

public void eatTrash()
    {
        if ( canSee (Trash.class))
        {
        eat(Trash.class);

            ((Counter) getWorld().getObjects(Trash.class).get(0)).add(-1);  

        } 

        }

Why do you have 'Trash.class' instead of 'Counter.class' in line 7?

that was a mistake, i forgot to change it back before copying it

#
So you have 'Counter.class' there? Does it compile? What is the error message?

"Nothing happens" means that the counter doesn't decrease or that the Trash doesn't disappear, too?
