Our neighbor swears by the all natural route...no skeeter/ticks/flea meds etc.Their GR passed at 9 and Molly was heavy at the end.She was fed human foods(chicken/vegetables) but no beef or pork.Just like humans,we all have different systems.I would kill for a few slices of pizza with hot peppers,anchovies and some hot wings...but I would suffer,really suffer.My great,long time bud in life could knock out half a pizza and a pile of wings without even burping.
