if you got a little skill then it should be posseble to do it on your own (i dont think that BMR777 coded it that hard :P)
i dont got the script yet , but i shal try to give you some help how you need to do it (i can be totaly wrong to :S)
the voting is linked to the pet
so every pet got there own votes
as you see the script of the pet , the file that shows the pet
then open that file and see where you see the text or lines that are like this
you will see probaly something like that (can be totaly differend to but it will looks the same way like that )
then just copy it , try to find the vote system on that page and put that code above it , and close it then
then it will only show when a user is logged in (or to that sertain group so a admin does not see it , if it works with groups :P )
hopes this small thing can help you
