I was contacted to make a review of PortionPRO RX, the ultimate selective automatic feeder that has been designed to feed a pet prescription food, allowing the assigned pet to eat and blocking the other pets from getting food.

Unpacking the PortionPRO RX
(note: I was provided 2 tags to make the review, but the feeder comes with one tag)
How it works
PortionPRO RX features a motorized sliding food door that opens when in contact with the cat’s collar tag, allowing the cat to eat the special food while blocking the other pets from eating.
The feeder features an RFID (radio frequency Identification) technology that senses the programmed “assigned” tag and opens the door when the allowed cat approaches the feeder within a 3-feet distance. Also, you can program a tag as “unassigned” which causes the opposite effect, when the unassigned pet approaches the feeder within 3 feet, the sliding door shuts, blocking the food.
PortionPRO RX feeder comes with 1 tag that you can assign or unassign, depending on the type of settings you want to program the unit, either Open Mode or Close Mode (you can purchase more tags if needed, I was provided 2 tags to make my review).
Selective Feeding Modes
Open Mode: This means the sliding food door will be open at all times so the cat who’s eating the special prescription food (or the cat that is being food bullied) can eat anytime from the feeder without the need of wearing a tag. The pet you want to block will need to use a tag programmed as “unassigned”. When an unassigned pet approaches the feeder, the door will shut, blocking the food. This mode is suitable in case you have a cat that doesn’t want to wear a collar tag.
Close Mode: The food sliding door will be shut at all times and will only open when in contact with the “assigned” cat tag. This setting requires all your pets to wear a collar tag which is the allowed cat, and the rest. In this case, you will have to program an “assigned” tag for the cat eating prescription food (or the cat being bullied) and an “unassigned” tag for the pet you want to block from eating. The reason for this is to make the door slide shut if the unassigned pet approaches the feeder while the assigned cat is eating. Over time the unassigned cat (or dog) will learn that if he approaches the feeder it won’t be able to eat from it, so it will let it alone. As the “Close Mode” requires the assigned cat and the other pet(s) to wear a tag, you need to purchase extra tags.
Programming Mealtimes & Portions
This feeder is meant to dispense dry food only, and you can program the unit for a cat or a dog. The liquid crystal LCD screen of the control panel makes it easy for you to program the unit.
LCD Panel & Buttons
The control panel features 3 buttons that are all you need to program the unit. The (+) and (-) buttons allow you to scroll up or down the options. The (√) button enters the selected option. If you make a mistake and need to go back, just press the (√) button for 2 seconds and it will take you to the previous step. The programming is easy because the LCD panel automatically shows you step by step what you need to do next.
Programming the PortionPRO RX for a cat
- Select the current time and choose the cat as the assigned pet.
- Program the # of meals you want your cat to eat per day. The feeder can be programmed to feed 2, 4, or 6 times per day. If you choose to feed your cat 2 or 3 meals p/day you must program the time for each meal, individually. If you choose 6 meals p/day you only need to program the time for the first meal and the feeder will dispense automatically a meal every 4 hours, starting from the hour you programmed and completing 6 meals in 24 hours.
- Choose the total amount of food p/day, from ½-cup up to 3 cups p/day. (Note: the feeder can also be set to dispense in ¼-cup increments from 3 cups up to 4 cups p/day, but you most likely won’t use this setting for your cat).
- Bind the tag with the feeder to “assigned” or “unassigned”. That’s all. The feeder is ready to feed your cat.
It’s important to mention that, unlike most feeders, with PortionPRO RX you don’t need to choose the portions individually for each meal. You only need to program the # of meals, and the total cups of food p/day and the feeder will divide the total amount equally among the # of meals you select.
½ cup p/day, 2 meals p/day= your cat will eat ¼ cup per meal.
½ cup p/day, 4 meals p/day= your cat will eat 1/8 cup per meal.
½ cup p/day, 5 meals p/day= your cat will eat 1/10 cup per meal.
¾ cup p/day, 2 meals p/day= your cat will eat 3/8 cup per meal.
2 cups p/day, 2 meals p/day= your cat will eat 1 cup per meal, etc.
As you can see with PortionPRO RX you can feed your cat very small amounts of food at a time and also large amounts of food per meal.
Programming for a dog
The feeder allows you to feed a dog 2 or 3 times a day. The programming of cups p/day is the same as cats with the difference that dogs can eat up to 6 cups p/day if you choose to feed your pet 3 meals p/day. This makes the PortionPRO RX suitable for small and large dogs since you can feed your dog from ½ cup of food p/day, to up to 6 cups of food.
You can trigger a dispensing manually and also open the sliding food door manually as well. To do this, the tag needs to be away at least 3 feet from the feeder. Check my video on how to set up and program the feeder:
PortionPRO RX Set Up & Programming
(note: I was provided 2 tags to make the review, but the feeder comes with one tag)
As you could see in the video, in order for the sliding door to open again to allow the cat to continue to eat, the unassigned pet needs to be at least 3 feet away from the feeder. On the video, I didn’t put the tag far enough so that’s why it took a little longer for the food door to open. When I put the tag further the door opened automatically.
A factory reset allows you to erase all current settings programmed in your feeder and clears the memory of any entered assigned tags. To do this unplug the feeder, hold (-) while plugging the unit back into a power socket. Once the feeder is plugged in, release the (-) button. All the current programmed settings will be deleted and you can reprogram the PortionPRO RX.
What are the Pros & Cons of PortionPRO RX pet feeder?
Here’s the list of pros and cons I found during my experience with this feeder. I found more Pros than Cons, which is good.
- Sturdy, well-made unit
- Food-grade materials that keep the food purity
- Easy to set up & program
- Clear liquid crystal LCD panel
- An effective mechanism of motorized sliding food door to protect the food
- The feeder senses the RFID tag when the unassigned pet is 3-feet away, not allowing the opportunity of food theft.
- Unassigned pet learns over time that the feeder is never opened, stopping them from trying.
- Much easier to program by deciding how much you want your cat to eat p/day in how many meals.
- The feeder allows to you feed your cat very small amounts of food at a time, good for cats that eat too fast.
- Accuracy in portions when dispensing
- Ceramic-coated stainless food bowl, is hygienic and prevents feline acne
- Easy to program the clock (12 hours am/pm)
- Removable feeding bowl, internal conveyor, and food bin
- Cat-proof lid
- Flap protects the food gate, stopping those mischievous paws from trying to steal food
- The feeder keeps all the settings if unplugged.
- It doesn’t have a battery compartment as a power backup
- You need to buy extra tags if you need to block more than one pet (with open mode).
- The door doesn’t open or close fast in case you have a cat that reacts quickly.
- Tags are hard to find available and they need to be replaced every 4-5 months. (UPDATE: The PortioPro comes now with a new replaceable battery for the tags and also a new zip-tie collar mount so you don’t have to replace tags).
- High price
In the beginning, the cat may get scared a little with the noise of the food sliding door. This is normal and he will get used to it.
PortionPRO RX is a high-quality selective RFID automatic feeder that I highly recommend. This feeder works as intended, locking out pets from accessing the food that is meant to be eaten for a specific cat or dog. The motorized food door works efficiently and it doesn’t jam. This unit will be a lifesaver in the following cases:
- To feed a cat (or dog) special RX diet in multi-pet households
- To stop food bullying between pets
- To feed a cat that eats too fast and vomits
- If you want to feed your cat very small portions, up to 6 times p/day
- To put a cat on a diet
- If you want a cat-proof feeder
- If your cat has feline acne
UPDATE (2022/2023): The PortionPro automatic feeder had some issues in the past with the tags not being sealed and having to be replaced every 4-5 months, with no availability to find tags either. The Company also had a 2-year interruption in their business due to Covid. Currently, PortionPro is back in the market with a new user-replaceable battery and a zip-tie collar mount to keep the tag away from the water bowl. This means the tag will be protected. Also, you don’t have to replace the tag anymore, only the battery. All in all, the tag’s flaw has been fixed which makes this automatic feeder an excellent unit because it has really high-quality materials. The brand just needed an adjustment of its tag. I recommend the PortionPro for all cats, especially for:
- Multi-cat use when you need to selectively feed one cat.
- To protect the food from frisky cats
