Whenever I try to challenge an opponent, it tells me that none of my pets are eligible to battle. When I look at my pets, it says that they are Very Happy and Bloated..

Shouldn't I be able to battle?

Check the status page to see if they are already in a battle. Or check if their hp is zero...other than that I think you'd have to file a ticket.

Looks like I forgot to end the battle last time.. haha. Thank you!
