YAY!!!!  I've been going to the Novartis website and looking for updates.  Their last one was on March 8.  When I went in to look about a week ago, that update page was gone.  I was hoping that was a good sign, and it is!  Thanks so much for the heads up.
 
I also read that they had received FDA approval to add praziquantel to the formula to treat tapeworm.  I wonder if they will have two different products, Sentinel and Sentinel Spectrum?
