I think I (and the kids) had a little too much fun with this!
PetCentric allows you to custom create e-cards using your own pet’s mug, and you get to choose the outfits, the mouth and the tune!
Since the flash on the cards starts automatically I’ve put my full card under the cut, if you want to see it. If you create one and load it to your site, leave a link here so we can see it!
