Quick Summary
These are compatible microchip collar tags for selected Closer Pets and Cat Mate selective cat flaps. The product is described as a replacement disc key type item, so the main buying point is matching it to the correct flap model and checking the exact included quantity before choosing an offer.
For buyers with a compatible selective cat flap, the key check is simple: make sure the model matches your existing unit, especially where the flap is listed as 305, 306, 355W or 360W. This keeps the product focused on the right use rather than a similar-looking alternative.
What to Compare Before Buying
- Compatibility: Check that your cat flap is one of the compatible selective models listed for this item.
- Variant: Confirm whether you need a collar tag, disc key or replacement key style item.
- Model match: Compare the flap model number carefully, as this is the main fit check for this type of accessory.
- Quantity: Check how many tags or keys are included in the selected offer.
Before You Decide
Confirm the exact cat flap model and the selected key or tag format before choosing an offer. If your flap is not one of the compatible selective versions, a different accessory will be needed.
