Pictures with multiple pets will not be approved and submitted into the competition. You must be the owner of the image you upload, or have explicit permission to upload and use that image. Once images are submitted to, they become the property of For more information, view the Terms & Conditions.
The Competition
The competition is composed of random match-ups between two members of the same pet category. Pets are chosen at random to face off against one another in a duel. There will be no end date for when pets can be submitted; however, there will be a minimum number of mandatory duels in order for a pet to move on to the next round. This number of mandatory duels will be determined when an average number of duels can be determined.

Scoring works as follows. Each duel can be a win, loss, or draw for either pet. The winner will add a win to that pet's overall record, and a loss will be added to the loser's record. A draw results in a draw being added to the record of both pets. The pets who advance to the next round will be determined by winning percentage. The winning percentage is calculated by the total number of wins divided by the number of wins and losses combined. Draws will not be counted towards the total number of duels when determining winning percentage. The pet with the highest percentage by the end of the competition will be declared the winner.
The prize for the monthly competition is $25. Each month, the pet with the highest winning percentage and a minimum of 200 duels will be declared the winner. Their owner will be sent a $25 prize via PayPal. Please note, PayPal is the only method with which will send prize payments. Please be sure to visit to register an account if you do not already have one, otherwise we will not be able to send you your prize.
Cheating/Voting Fraud
All users are, of course, allowed to vote for their own pets. However, it is against the rules of the competition to declare draws until seeing your pet(s) and only voting in duels in which a pet of yours appears. Additionally, any problem in the voting system (such as being able to have multiple votes cast from a single random duel) must be brought to the attention of by contacting us. Use of a flaw in the voting system constitutes cheating.

Any attempt to defraud, deceive or compromise the integrity of the competition is a form of cheating or voting fraud. Users found to have done this will have their pets disqualified from the competition and will not be awarded a prize of any kind. Please note - you may not be contacted about being a known cheater until after the competition is over. Therefore, it may appear as though your pet has won at the end of the competition, but if it is found in a review of the votes that dueling for your pet was illegitimate, your pet will be disqualified after the conclusion of the competition. Please note that if you are simply dueling to propel your pet(s) up the leaderboard, this is cheating and will earn you pet(s) a disqualification from the competition.
