How it Works

Learn How the PortionProRx Works

The PortionProRx is an innovative pet feeding solution that uses RFID technology to prevent food-stealing between pets, while controlling meal portions. The PortionProRx Automatic Feeder for cat & dog feeds the right pet, the right food, in the right amount, at the right time, every time!

Note: Feeders are intended to be used by one pet for proper daily meal portioning. Each pet should wear a tag for access control. If purchasing less feeders than pets in the home be sure to add extra tags to your cart.

    The food gate senses not only if the bowl is full, but also if a pet is trying to steal extra food. If Snowflake tries to get a paw up to steal extra kibble our anti-theft system is triggered and the door will close to prevent any food stealing.

    PortionPro Pet Safe Design control

    Pet-Safe Access Control Design
    With pet safety as one of our main goals we designed the PortionProRx with several safety features. One of these is the door which closes at a low force and also senses when anything is in the way to avoid hurting any pets (Notice the marshmallow in the picture was not damaged after the door closed on it).

    Between the wide base and rubberized footing the PortionProRx is designed to make it very difficult for your pet to knock over. Add in the weight of the kibble in the food bin and we'd love to see Toto try!

    How it Works

    Step 1

    PortionPro quick setup

    Quick Setup

    Following our Quick Start Guide programming your new feeder only takes a few minutes.

    Step 2

    PortionPro Pet Identification System

    Attach the Tag

    After programming attach all the tags appropriately onto your pets' collars.


    • The RFID tag that comes with the PortionProRx uses our own patented Pet Field Communication technology to control pet access.

    • Tags have a battery life of ~1 year (depending on the activity of the pet, could be 7 or 8 months) and are water resistant up to 3 feet.

    • Every pet in the home should wear a tag on their collar for access control.

    • All tags are by default unauthorized to any feeder. Only tags that you authorize during programming are approved by particular feeders.

    • If purchasing less feeders than you have pets in the home you'll want to purchase additional tags in our store to ensure they all have a tag.


    Step 3

    PortionPro quick setup

    PortionProRx Delivers Food

    The proper amount of food will be dispensed at the time and in the amount you programmed.


    • The PortionProRx delivers anywhere from 1/2 cup to 6 cups of dry food DAILY. We recommend 5/8's of an inch diameter or less for best accuracy and food delivery.

    • For dogs you choose either 2 or 3 meals per day.

    • For cats you choose either 2, 4, or 6 meals per day. 6 meals is automatically divided over a 24 hour period and is the optimal setting for cat health as they get small frequent meals.


    Step 4

    PortionPro quick setup

    Authorized Pet Approaches

    The door stays open whenever the authorized pet is around to allow them to enjoy their meal.


    • If your feeder is in open mode the door will remain open.

    • If your feeder is in closed mode the door will open allowing access to the food bowl and stay open for 20 seconds after the approved pet walks away.

    • The authorized pet has access to the food bowl anytime of the day whether there is food in it or not. We control how much food the pet gets and what time they get it, not how they choose to access it.


    Step 5

    PortionPro quick setup

    Unauthorized Pet Approaches

    The door closes when any unauthorized pets are within 2 feet to prevent food stealing.


    • Not allowed to access food in the feeder.

    • In our test studies even the most aggressive food stealers lost the behavior within one week.

    • Our active RFID system shuts the door from 2 feet away to ensure no food stealing can occur.

    • After an unauthorized pet leaves the feeder area the door will remain shut for 20 seconds to ensure they lose interest and don't guard the feeder.


    Step 6

    PortionPro quick setup

    Sit Back and Enjoy

    All you need to do now is enjoy effortless mealtimes as the PortionProRx takes care of everything!


    • Keep an eye on the food bin to ensure it stays nice and full so your furry children continue to be fed. (An alert will let you know if the food bin goes empty)

    • Occasional cleaning is suggested and very simple. All parts that touch the food are removable and easy to clean.


    In Action

    The PortionProRx is an advanced feeding system that controls the amount of food your cat or dog is fed in a day. It is intended to be used to feed one pet in the home while restricting access to all others. In this way the PortionProRx makes sure that only the appropriate pet is eating the food meant for them.

    Extremely Durable

    Unlike many flimsy and easily breakable pet feeders on the market, the PortionProRx was built to a professional standard. Watch our video and see just how much abuse the PortionProRx can withstand.
