New formula, bigger pieces, seen as inedible
Our two cats get Purizon dry food as a topping for their wet food, for games that use dry food/treats, and so on. So far, they've eaten all the Purizon varieties, but they absolutely won't touch the lavender one. The pieces are also much bigger than the other types (which wouldn't bother me), but overall it's a completely different food. The only other time they've refused food like this was with an opened pack of cheap supermarket food we were given as a gift.
