My vet gave me Fortiflora for my cat Pixie, who is having soft stools and diarrhea. The box says to mix it with food, but Pixie won't eat the food with it mixed in. Weirdly, she will lick it up off a plate if it's by itself. She's already a picky eater, so I don't want to turn her off the couple of foods she will eat. Is there any harm in allowing her to lick up the Fortiflora, then feed her the meal?
