That's really good news that she is Ok. She must have been happy to see you. I'm not clear whether the vet associated with Petsmart had a look at her. If Binky is still underweight and not well, I would give her handfeeding formula and see about vet advice. Perhaps there won't be a charge for phone advice.
From what I understand, there are two issues happening with Zupreem...the past recall in about 2012 for having too high calcium levels in their pellets; and the unresolved January 2018 issue relating to the Bird and Beaks Rescue incident (their facebook page has updates), but there is no zupreem or lafaber recall happening for that. Over the phone, when they said "no recall", they were likely referring to the 2018 incident.
