Sorry if this has been answered already, but I couldn't find it.

If you zap a pet with items in their treasure, is there any risk that you might zap the items? Would be good to know before I zap any pets with a full treasure chest.

Nope. You might get an increase in TC slots but you won't risk the items.

Okay, thank you.

Oh God, the rage that would rise up from the userbase, I can't even imagine XD
