0 The cat is in disguise as a bee. The birds obviously weren't fooled last time. One bird is warning the other that the cat now has a sting as part of his bee costume. I have no idea if the bird is saying it with pity - as if to say, "the disguise is still rubbish, I can't believe he thinks we'll be fooled"; or with caution - as if to say "watch out, he has a weapon this time". 0-
