You can use cron jobs or php, to change the pets image over time, I don't know how to remove clicks without messing up the adoptable script, but this may create a lead. This is a script I have for my own pet system I made. It makes the adoptables image change.
Just putting it out there as a resource to do this ^^;

This is a image.php?id=3
it shows a pets image depending on the id number of the pet.
You would need to add babyurl , teenurl , adulturl in your speices table..I think you probably already have that but with a diffrent name.
In owned adoptables table you should add
`date` varchar(255) NOT NULL,
`fulldate` varchar(255) NOT NULL,
`halfdate` varchar(255) NOT NULL,

function greaterDate($dformat, $beginDate, $endDate)
{
    $subtract = $endDate - $beginDate;
    if($subtract > 0) {
    return 1;
    }
    else {
    return 0;
    }
}

function p_image($url) {
//edit line below
return './adoptable image dictionary/' . $url;

}
function check(){
//pid is the adoptables id being requested
$pid = mysql_real_escape_string($_GET['id']);
$result = mysql_query("SELECT * FROM `OWNED ADOPTS` WHERE `id` = '{$pid}'");

while($row = mysql_fetch_array($result, MYSQL_ASSOC))

{
//petid is in owned adopts table, it is the id of the speices adopted.
$results = mysql_query("SELECT * FROM `S P E C I E S` WHERE `id` = '{$row['petid']}'");
$pet = mysql_fetch_array($results);

$results2 = mysql_query("SELECT * FROM `U S E R S` WHERE `id` = '{$row['owner']}'");
$user = mysql_fetch_array($results2);

if(greaterDate(".", $row['fulldate'], date('Ymd')) > 0) {

$im = p_image($pet[adulturl']);
$image = imagecreatefrompng($im);
header('Content-type: image/png');
return imagepng($image);
return imagedestroy($image);

} elseif(greaterDate(".", $row['halfdate'], date('Ymd')) > 0 && greaterDate(".", $row[fulldate], date('Ymd')) <= 0){


$im = p_image($pet['teenurl']);
$image = imagecreatefrompng($im);
header('Content-type: image/png');
return imagepng($image);
return imagedestroy($image);

} elseif(greaterDate(".", $row['halfdate'], date('Ymd')) <= 0){

$im = p_image($pet['babyurl']);
$image = imagecreatefrompng($im);
header('Content-type: image/png');
return imagepng($image);
return imagedestroy($image);

}
}
}

echo check();

In the file where you adopt your pets, you would add

$date = date('Y/m/d');
$halfdate = date('Ymd') + 7;
$fulldate = date('Ymd') + 13;

Adjust the 7 and 13 however you want..thats the number of days to grow. You simply just add the $date,$halfdate,$fulldate to the sql that insert's the adoptable info into owned adoptables.
Sorry I can't give a mod for this, its just a resource to whomever can complete the job.Keep in mind its not very secure and may need some edits :S
