This morning I found 2 big fat slugs like cork screws around each other doing the nasties. They were hanging from a twig.
How many can say they've seen slugs mating? I've seen small pets including fish, different insects and flies, but this is pretty rare.
I've heard that porcupines do it standing on their front legs so they don't stick each other. Rabbits are really funny to watch because after doing it the buck falls off and screems in joy. At least I assume he's not screeming in pain.
