The Pet Ultimates probiotics is 5 billion CFU which isn't much. If you're giving less than the suggested 1/8 teaspoon dose, it likely has no effect on the cat. It's hard to use probiotics with dry food since you can't mix it in. Do your cats like tuna? Milk or cat milk?
I use a Human probiotic, Renew Life 50 billion CFU. A capsule is split between the two cats. Neither of them notice the probiotic mixed into their raw food.
