Another ? from the Kitsune

I didn't know a short title for it to explain it :/ The way I have my site is that you click the adopt instead of using the form.

PHP Code:

if($canadopt == "yes"){  
            //If we can adopt the adoptable, show the image and adoption link...  
            $article_content .= "  
            <td  VALIGN='top'><br><br><br><br><br><br><br><br><br><br><a href='doadopt.php?id=".$aid."' onclick='canclick()'><img src='picuploads/png/e42598f988b271a7e66b36b9a5d8143b.png' /></a><br>  
            {$description}</td>";  
        } 


If a member knows the adoptable id they can just type that into the end up the doadopt url and receive that egg. How can I prevent this?
