You click on Hunt a Critter and then click the pets that show on that page, there are 30 each time I believe. Finding the hunted creature is completely random, you may find it on the 10th click, or on the 1000th click, there's no way of knowing. Just click continue hunting after you've clicked each set. Remember to click on the coin pouches when they appear for extra coins. If you've found the hunted creature it will be sent straight to your profile so you can't accidentally miss it.!!!!!!!!!!
