For some reason it says none of my pets are eligible to battle, even though Spardel is very happy and bloated, and I was battling with her not so long ago, anyone have any ideas?

happy and bloated and has hps? hmm ... it's not already in a battle is it? you can check by going to the statistics page.

Now I feel silly, thanks so much :P

not a problem. happens to all of us at one time or another. :)

Don't feel silly! This answers my question too! Ha ha!
