fake latin quote

I just got a cat cookbook called 'Real Food for Cats' by Patti Delmonte. There's a foreword that ends with 'As the Romans, who first domesticated cats to guard their granaries, used to say: Symbiotica et sympatico hominum philapussicat est.'

I can't find anything resembling this quote online, nor the word 'pussicat.' I think the guy who wrote the forward may have just pulled it out of his butt. I'd appreciate hearing your thoughts on this.
