Thanks everyone for the kind words. This isn't the first insensitive rabbit-related comment that this person has made. I think she grew up with having them as food, she made a comment "oh I must remember these are pet rabbits, and not for the pot". I guess she "forgot" again.
Perhaps I should leave this on her desk:
We are fancy rabbits, and believe it or not
We are fancy rabbits, not destined for the pot.
We don't intend to play, that special one-time role
In your quite disgusting, rabbit casserole.
Listen friend, it's time- that you got a clue
That we will never feature, in your rabbit stew.
And if you share your life, with a fluffy bunny
You will soon discover, that it's not remotely funny
To suggest that such a loving creature
should become the starring feature
Of your special party dinner,
Well that's really not a winner!
Those joke you make about me, I've heard them all before
To be honest friend you're unoriginal, quite a frightful bore!
Therefore in conclusion
To avoid any further confusion
I'll say again my friend and this will be the end
That we are fancy rabbits, and believe it or not
We are fancy rabbits, not destined for your pot.
