Kitten SOS. How to stop her eating from the dispenser?

Here is my situation I have two adult cats that eat from a dry food dispenser Hills Science Diet Prescripting Diet Feline Multicare CD. My other one eats from her bowl purina adult cat food and her canned. Now this is the situation I have a blue girl who is 8 months old she is supposed to be eating her kitten canned and dry food but now she is eating from the dispenser that my two adults are eating and ignoring her kitten dry food. I need suggestions on how to deter her from eating the food from the dispenser

Hmm - that's a tough one :scratch:

I've never used a food dispenser. Giving this a bump in the hopes that someone else can help you

place it up high enough that the adults can reach but not the kitten.
