No difference except in the name. The only people who care about it are collectors.
For example, and unplaced Penguin Pad is simply titled Penguin Pad. Once you place it and dig it back up, it is now titled Lvl 0 Penguin Pad.
Basically it's like the difference between an item still in its sealed package and something that has been used. I personally do not care about unplaced pets, but some do, and that's fine :)
