Yes, it can still happen. A selective feeder recognizes an authorized pet, but the surrounding setup also matters: another cat may approach while the bowl is open, reach from an exposed angle, or take advantage of an incorrectly configured lid. Investigate the access route before assuming the reader itself has failed.
Treat selective feeding as a system with three parts: the right identity is recognized, the food opening behaves correctly, and the intended cat can eat without being crowded out. Passing only the first check does not prove the whole arrangement works.
Work out how the food is being reached
Observe from a comfortable distance during an ordinary meal. If you record video, aim it at the bowl and approach route, not just the cat’s face. Do not encourage the other cat to intrude for a test, especially when a prescribed diet is involved.
| Observation | What to investigate | Safe next step |
|---|---|---|
| Wrong cat opens the closed feeder alone | Stored identities and pairing | Review the authorized-pet list using the manual |
| Wrong cat joins while the right cat eats | Shared access around the opening | Separate stations and ask support about approved barriers |
| Food remains exposed afterward | Training mode, obstruction, lid seating | Check the exact model’s normal operating procedure |
| Intended cat leaves when the other approaches | Location and social pressure | Return to supervised separation |
| Problem began after cleaning | Reassembly or a misplaced part | Reassemble according to the manual before reuse |
This is a troubleshooting checklist, not a diagnosis of a particular unit. Mechanical damage, unreliable recognition, or abnormal movement should go to the manufacturer rather than being worked around.
Training mode can look like a security failure
During introduction, a feeder may intentionally leave the opening less restricted so the cat can learn to use it. That is different from its normal access-control behavior. Sure Petcare provides a staged training function for its Microchip Pet Feeder; use the instructions for the exact device instead of a button sequence copied from another model. Official support.
Before declaring the feeder ready, confirm that it has exited training mode and that the correct cat uses it comfortably in normal operation. Do not rush this transition simply because food protection is urgently needed. Keep meals physically separated while training continues.
Placement matters, but do not build a trap
A station should not become a narrow corner where the intended cat cannot comfortably withdraw. Avoid positioning the two feeders as a single shared resource that one cat can guard. Give each station its own practical approach space.
If the manufacturer offers a rear cover or another compatible accessory, check its intended use and exact model fit with support before buying. Do not assume every cover blocks every type of intrusion. Avoid homemade lid weights, taped sensors, sharp barriers, or modifications to closing mechanisms. Those changes may introduce a new problem while hiding the old one.
Microchip and collar-tag compatibility are not the same
Read the identification requirement before troubleshooting. A collar-tag system is not necessarily an implanted-microchip reader. PETLIBRO’s One RFID, for example, requires its supported collar-tag approach and does not recognize implanted microchips according to its official compatibility FAQ.
That distinction matters when replacing a lost tag or moving from a different brand. Do not assume an existing tag will pair because both products use the term RFID.
What evidence should you send support?
Send the model number, a short description of the access route, the operating mode, and a short video if requested. Explain whether the wrong cat opens the feeder alone or reaches in only while the intended cat is present. Those are different problems.
Include when the behavior started and whether cleaning, battery replacement, pairing, or a settings change preceded it. Avoid factory-resetting repeatedly before support has reviewed the symptoms; you may remove the configuration information needed to understand the issue.
When to stop relying on it
If unwanted access continues, return to supervised separation while you investigate. Do not keep a failed setup in service merely because the product description promises food protection. A feeder is useful only if the actual household arrangement works.

Send support evidence of the access route
A feeder “not working” report is more useful when it explains how the wrong cat reaches the food. Observe without creating a confrontation or trapping either cat.
| Decision or record | How to apply it |
|---|---|
| Recognition | Which tag or microchip was present, whether training mode was active and the indicator state. |
| Access route | Front, rear, side or following the intended cat through; photo or safe video if available. |
| Setup | Exact model, approved accessories, placement and the last change before the problem. |
Provide the protected meal by another supervised method until access can be trusted again. Keep diagnostic facts separate from assumptions about whether a reader, lid or positioning fault is responsible.
