Four out of five butterflies hatched. One was eaten by the cat, who was so entranced with the fluttering within the habitat she knocked it down. One was injured by the habitat being pushed off the shelf in said butterfly-eating incident. So, two.
Two butterflies were released into our garden (they are a native species, and we had always intended to release them). We said a happy goodbye to them as they fluttered off into the garden (too quickly for my useless camera/skills), and we trooped back inside to scold That Bad Cat.
I somehow can't quite bring myself to raise butterflies again. Not for a while, anyway. Or perhaps, not in the lifespan of the Pet From Hell. :S
