Bummer, sorry to hear that. I've never observed my potters to nip at SPS. Although I can't keep SPS at the moment. Hmmmmmm. Although I'm reasonably certain the potter's isn't to blame .. but still, geez it seems like an awful coincidence.
Maybe she's just sampling, and once accustomed to the good stuff (ie. whatever you feed them
, will prefer that over the SPS.
