Can't battle in Arena because all the pets offered to battle are stuck in Battle or trades. An Auto kick system for pets unavailable to battle or to not show up would really help.

Could you please elaborate what exactly is wrong? Pets that "stuck in Battle" are the only pets which you can fight on Arena. You can't fight a pet until it gets "Fighting" status. If you mean Manual battles, then they are automatically cancelled after 5 minutes of inactivity from both sides.

And pets who are in Trades can't be applied to a battle at all, they can be offered to you as battle opponents.

Sorry, I really don't understand what is wrong with either of these statuses.

I put two different Pets into the Arena yesterday Every animal that shows up was unavailable even after 5 minutes. The ones that were "available" ( via the select circle was clickable ) the notice pops up " Can not battle this pet because its in another battle or in trades" 3 pages of the same Pets even after refreshing. So what I mean Is. If the animal is in another battle make it so it doesn't show up at all. its rather frustrating after a while trying to figure out whats actually available and whats not.

The notice that you mentioned appears when your pet is busy with trades or another battle, not your opponent. You simply can't apply a pet that is currently busy, nothing else. Please finish all the activities on your pet and make sure that its status is "Active" before trying to apply. All pets that are currently on Arena are available for fight.

odd alright. Thank you then.
