Microchip Cat Feeder vs Automatic Cat Feeder: What's the Difference?
Both dispense food automatically — but they solve very different problems. Here's how microchip feeders and automatic feeders differ, and which one you actually need.
Walk into a pet shop or browse online and you will find two categories of product often grouped together under "automatic cat feeders." They look similar. They both involve feeding cats without you standing there. But they solve completely different problems.
Understanding the difference will help you avoid buying the wrong thing — which is a very easy mistake to make.
What Is an Automatic Cat Feeder?
An automatic cat feeder dispenses a set portion of dry food at a programmed time. You fill the hopper, set the schedule, and the feeder opens to release food at the chosen times.
What it does:
- Feeds your cat on a schedule when you are not home
- Portions meals accurately
- Prevents cats from going hungry if you work long hours or travel briefly
What it does not do:
- Know which cat is eating from it
- Prevent one cat from eating another cat's dispensed portion
- Separate cats with different dietary requirements
An automatic feeder is essentially a timed bowl. Any cat in the household can eat from it. This is fine if all your cats eat the same food and you just need the convenience of automated timing.
What Is a Microchip Cat Feeder?
A microchip cat feeder reads your cat's implanted microchip (or a lightweight RFID collar tag) and opens the food cover only when the authorised cat is in front of it. The lid stays closed for every other animal in the household.
What it does:
- Identifies each individual cat
- Opens only for the authorised cat
- Keeps food protected from other cats (and dogs, in mixed households)
- Works regardless of whether you are home
What it does not do:
- Automatically dispense portions at set times (most models — some hybrids exist)
- Work with large kibble pieces or very wet, liquid-heavy foods (depending on the model)
- Prevent the authorised cat from eating more than its allocated portion (unless a portion-control version is used)
A microchip feeder is a selective access device. The automation is about identity verification, not timing.
The Key Difference
Automatic feeder: Solves the timing and portioning problem. Does not solve the who-is-eating problem.
Microchip feeder: Solves the who-is-eating problem. Does not necessarily solve the timing problem.
If your cats eat the same food and you just need a feeder that works while you're at work, an automatic feeder is appropriate.
If you have cats that need different foods — or if one cat steals the other's meals — a microchip feeder is what you actually need.
When Each Is the Right Choice
Use an automatic feeder when:
- All cats eat the same food
- You need scheduled feeding while away from home
- You want consistent portion sizes without manual effort
- No cat in the household has a special diet
Use a microchip feeder when:
- One or more cats is on a prescription diet
- One cat is stealing another cat's food
- Cats need different portion sizes
- You have a cat with a medical condition that requires strict dietary control
- You want to protect a specific cat's food around the clock
Use both when:
- You need automated scheduling (automatic feeder for timing) and diet separation (microchip feeder for identity-based access)
- One cat gets an automatic feeder for regular food; another cat has a microchip-protected bowl for prescription food
Hybrid Devices
Some products combine both functions — a microchip-enabled lid on a portion-dispensing automatic feeder. These are typically more expensive and have mixed reviews, particularly around reliability of portion control and lid mechanisms.
Another approach is what the Aiwan Cat Food Shield offers: a microchip-activated cover that sits on top of your existing bowl or feeder. Instead of replacing your setup, it adds selective access protection to whatever you already use. This means you can keep your existing automatic feeder for timing and add microchip protection on top.
Does a Microchip Feeder Work Without a Microchip?
Most microchip feeders also come with RFID collar tags for cats that are not microchipped. The tag functions the same way as an implanted chip — the feeder reads the tag and opens accordingly.
If your cat is not microchipped, you can still use a microchip feeder with the tag system. Microchipping is generally recommended regardless (it is the most reliable form of permanent identification if a cat is lost), but it is not required to use a microchip feeder.
Price Differences
Basic automatic feeders start at around $30 to $50. Mid-range models with better portion accuracy, app connectivity, and larger hoppers run $60 to $150.
Microchip feeders are typically more expensive — most quality models start at $80 to $120. Products with both automatic dispensing and microchip identification are at the higher end of the range.
The price difference reflects the complexity of the technology. If your situation requires diet separation, the cost of a microchip feeder is usually small compared to the ongoing cost of managing a cat's health condition without one.
Frequently Asked Questions
Can I use one automatic feeder for two cats?
If both cats eat the same food and you're comfortable with them sharing access to the same portion (or two separate portions from a dual-bowl model), yes. If they need different foods or different portions, a standard automatic feeder is not sufficient.
Do microchip feeders work with all cat food types?
Most are designed for dry food and wet food in standard form. Very liquid wet food may not sit well in certain feeder designs. Check the product specifications — some are designed specifically for wet food.
My cat doesn't eat quickly. Will a microchip feeder work?
Yes. Microchip feeders do not require the cat to eat quickly. The lid opens when the cat approaches and closes when the cat leaves. A slow eater can return to their bowl repeatedly.
Can I register more than one cat to the same microchip feeder?
Most microchip feeders allow you to register multiple chips to a single feeder — useful if you want two cats to access the same bowl. Check the specific product for how many chips can be registered.
If you have been using an automatic feeder and wondering why your cats are still eating each other's food — that is why. The automatic feeder was solving the wrong problem. Microchip technology is what addresses identity-based access.
For households needing both scheduling and selective access, the Aiwan Cat Food Shield adds microchip protection to your existing feeder without replacing it.
