Should the Roman Pontiff suppress ermine-trimmed vestments?

The Italian Antivivisectionist League at the University of Pavia, where the Holy Father will visit on the 22nd, have issued a press release (that La Stampa has dignified by taking notice of) calling on his Holiness to give up the use of ermine to adorn the pontifical vestments, saying that "this would be a praiseworthy example of Christian charity, all the more significant since done by the highest ecclesiastical authority". 

While I suspect that good Pope Benedict respects the League's invitation to the exercise of the virtues, I also doubt that his Holiness understands the doctrine of man's dominion over Creation in quite the same way that it does.
