This week's addition to The Science of Kissing Gallery features the collection's second interspecies kiss! (and LOLCats fans are encouraged to offer headline suggestions in comments!) Gabrielle Stern reminds us that, "Some receivers of kisses aren't as gracious as others. Here's my cat and I. Clearly, I'm more affectionate than he is, which often makes for fun pictures." Thanks to both of you for such an expressive photo! Submit your original photograph or artwork to the gallery here and remember to include relevant links.
