Has anyone used the Primal raw goat milk as a supplement for older picky cats? My 13 year old super finicky cat seems to be turning his nose up to his raw food I've never been able to get him to eat any wet food, just raw, so I'm upset that he's now refusing it. He's eating good quality kibble (tiny amount of Orijen mixed with Ziwipeak air dried) but I'm trying to keep him hydrated and I was thinking about trying their goats milk.
