Hi, I played with a Blue basket with my pet, but didn't receive the achievement, why?

Try going to your pet pages. Also, sometimes, achievemtns wont actually pop up, but they're there on the achievement page. Have you looked under "pets"?

Did you get the item back? If you pet is happy and doesn't actually play with the item (it should leave your inventory) it won't count :(

yes, the item is in my inventory. How can I make my pet play with the toy?

One of your pets needs to be Depressed in order to play with the toy.

When you give them the toy it should say something like:

X says: Wheee! I love to play with that!

If your pet is too happy, it will say something like:

X says: Err... that was SO boring!

my pets are all very happy :-D

Try taking away a minion from one of them and waiting a day or two, they should become sad C:

I'll try, thank you :-)
