if you uninstall you can manually remove those entries from the ones that failed
in Shop.english.php you would need to remove this

and in Shop-Subs.php remove this code
function check_Pets() {
global $db_prefix, $sourcedir, $modSettings;
$date = date('z');
if ($modSettings['shop_pets_date'] != $date) {
require($sourcedir . '/shop/pet_engine.php');
if ($handle = opendir($sourcedir . "/shop/pets_breeds/")) {
while (false !== ($file = readdir($handle))) {
if (substr($file, -4) == '.php')
{
// Get the breed name (file name without .php extension)
require($sourcedir . '/shop/pets_breeds/' . $file);
}
}
}
$result = db_query("SELECT * FROM {$db_prefix}shop_pets", __FILE__, __LINE__);
while ($row = mysql_fetch_assoc($result)) {
eval('$temp = new pet_' . $row['breed'] . ';');
$temp->load_values($row['pet_id']);
$temp->advance_day();
$temp->store_values();
}
$result = db_query("UPDATE {$db_prefix}settings SET value = {$date} WHERE variable = 'shop_pets_date'", __FILE__, __LINE__);
}
}
thats if you feel confident to edit the files just make backups of them before you do so you can quickly recover if something goes awry
EDIT: Removing the above bits of code might not even be necessary but if it were me i would do it just in case
