Matt, no puncture wounds that we can see. We did do a google search and it did say Benadryl in the exact amount you said, so far hes has got two doses of it hes starting to look better thank goodness, poor little guy. Ok back to your cake, i would first tell you to use high ratio shortening when you make your BC it makes a world of difference. I would first smooth the cake out , than like already said use a spoon pulling it straight up the sides of the cake wiping the spoon off as you go. Buy a heart shape cookie cutter for the heart and let your Bc crust up than press the cookie cutter in just good enough to see the outline of the cutter. Michaels craft stores sells white almost clear cake glitter in there cake department , sprikled on this cake would give a beauiful look.
