My pet won't play with any of the toys I get her, It's really getting annoying. Fickle little beast.

Pets won't play with items if their mood is at very happy. Only time they'll play with anything is if their mood drops below that.

Wait I just noticed she's happy. odd I haven't played with her in weeks.

Is she in the lodge/resort? or have a minion? those both make your pet happy...

She does have a minion. hmmm I see this is working out well.

yup, minions make the pet permanently happy!

moving this to help and questions.

There's actually a glitch, where your pet stays happy all the time. Try removing the minion and see if the mood decreases. If it doesn't you could also try using (borrowing) a maleria's clawed glove, and make one of your other pets use it during battle... it makes all your non-battling pets depressed 8'D
