Microchip Feeder vs Automatic Feeder
These two machines look like competitors and solve unrelated problems. Buying the wrong one is the most common feeder mistake in a multi-cat house.

Everyone in this category says they tested twenty litter boxes. We have not tested any, and we say so. What we do instead: compile the published specs, read the manuals, and do the arithmetic on what this gear costs to run and how it behaves once there is more than one cat using it. Every spec is linked to the document it came from. Prices are checked daily — last verified September 27, 2026. Here is exactly how we pick.
Both machines sit on the kitchen floor and both have a lid that moves. They answer completely different questions, and the question you actually have decides which is money well spent.
Two different problems
A microchip feeder answers who. It reads the cat’s implanted chip or a collar tag and opens the lid only for that cat. Food can sit down all day and still belong to one animal.
An automatic feeder answers when and how much. It holds a reservoir of dry food and drops measured portions on a timer, whether you are home or not. It has no idea which cat is standing in front of it.
What the two publish

| Portioning | None -- you fill the bowl | 1/8 cup to 4 cups, up to 12 meals a day |

Manufacturers' published figures.
What separating two diets actually costs
A SureFeed stores up to 32 identities, which sounds like a multi-cat solution. It is not, because it is still one bowl: it opens for any registered cat that approaches.
To keep cat A out of cat B’s food you need two units, each registered to one cat. The 32-identity figure is about which cats are allowed at a given bowl, not about serving several cats from one.
So the honest budget for two separated diets is two microchip feeders plus the floor space for two stations, ideally out of sight of one another. Our different diets page lays out that layout.
The gear discussed here
The SureFeed Microchip Pet Feeder is the access-control option, and the wet-food capability is what sets it apart: a 400 ml sealed bowl means a pouch can sit down without becoming a free buffet. The honest cons: it does no portioning at all, it runs on 4 C cells rather than mains, and you need one per cat you are separating.
The PetSafe Smart Feed is the scheduling option, with a genuinely large 24-cup hopper and portions from an eighth of a cup up to four cups across as many as twelve meals a day. The slow-feed mode spreading a meal over 15 minutes is the feature most owners end up using. The honest cons: dry or semi-moist food only, and no ability whatsoever to tell your cats apart.
Which one your house needs
- One cat, and you are out all day: automatic feeder. Portion control and timing are the whole problem.
- Two cats, same food, one eats too fast: automatic feeder plus a slow feeder bowl, or the slow-feed dispensing mode.
- Two cats, different food: microchip feeders, one per cat. Nothing else solves it.
- A cat that needs wet food left down safely: microchip feeder, or a refrigerated unit from our wet food feeder page.
- You want to know who is eating what: a camera feeder answers that before you spend on access control. Our camera feeder page treats it as a diagnostic instrument.
Compare the two
If you remember one line from this page: a hopper cannot tell cats apart, and a microchip lid cannot tell time. Decide which of those two failures is the one happening in your kitchen, and buy the machine that fixes it. Before either arrives, our introduction guide covers the week that keeps a cat from rejecting the thing outright.

SureFeed Microchip Pet Feeder
Sure Petcare · Microchip feeder · Our score 8.5/10

#ad Price as of September 27, 2026. Prices move; we check daily. How we're funded.
The only feeder here that solves the actual multi-cat feeding problem, which is not portioning -- it is one cat eating another cat's food.
Published specs
| Bowl capacity | 400 ml, or two pouches of wet food |
|---|---|
| Pets stored | Up to 32 identities |
| Food types | Wet and dry |
| Power | 4 x C cells, 6-month stated battery life |
| Warranty | 3 years from date of purchase |
| Opens for | Registered microchips or a collar tag |
Source: Sure Petcare -- SureFeed Microchip Pet Feeder product page
Sure Petcare states 6 months from a set of 4 C cells, so 8 cells a year per feeder. In a three-cat house you need one feeder per cat on a controlled diet -- 24 cells a year for three. That is the running cost nobody mentions.
What the specs favor
- Stores up to 32 pet identities -- more than any household needs
- Works with an existing microchip, no new collar required
- Takes wet food, which almost no automatic feeder does
- Three-year warranty, the longest here
What they don't
- Battery only -- 8 C cells a year, per feeder
- One feeder feeds one cat, so a three-cat house needs three
- 400 ml bowl is a meal, not a hopper -- it does not solve holidays
Your problem is being out all day rather than food stealing. This is a lid that opens for the right cat, not a scheduled dispenser -- it will not feed anyone at 6pm on its own.

Published specs
| Hopper capacity | 24 cups (6 L) |
|---|---|
| Portion range | 1/8 cup to 4 cups |
| Meals per day | Up to 12 |

24 cups of hopper. Three cats eating half a cup each per day is 1.5 cups daily, so about 16 days. The slow-feed setting spreads one meal over 15 minutes, which is the published feature that matters if one of your cats inhales food and then takes the other's.
What the specs favor
- Largest published hopper here at 24 cups
- Portions from 1/8 cup to 4 cups -- the widest range on this page
- Slow feed spreads a meal over 15 minutes
- All food-contact parts are dishwasher safe
What they don't
- Single bowl, so no separation between cats
- Dry or semi-moist only
- 20 inches long -- it takes real counter or floor space
You feed wet food. Nothing about this feeder handles it, and leaving wet food in an open bowl on a timer is a food-safety problem, not a convenience.
