My active pet won't appear in the drop down menu for the battle coliseum at all but he is not hungry, board, or engaged in battle. He is booked in at the resort but so is my second pet who is available for battle? Please help

Have you healed or fed your pet recently? Like, sometimes it just takes a minute for pets to show up after being healed from 0 HP, or being fed from being hungry

nope not at all

And you double checked that your pet is full, happy, with at least one hit point and for sure isn't in battle? I think I've gotten stuck before because I defeated my opponent, then clicked somewhere else before going to the "see results" page

If it's none of these things, then I suggest filing a ticket

i know for absolute sure he is full health and not hungry or bored and he doesn't seem to be in battle. I lost my last battle. Perhaps I am stuck too? How to get unstuck?

If you go here: http://subeta.net/games/battle/stats.php it'll show you if your pet is in battle.

thank you he was stuck in battle I got him unstuck

Yay! I'm glad it worked. Good luck battling! :)
