Start with the neck measurement, not the collar
A cat collar only works as a safety tool when it fits properly. Before you adjust the Red Dingo Cat Collar Fish Bone Dark Blue, measure your cat's neck circumference where the collar usually sits. Compare that number to the size chart supplied with the product. The collar is length adjustable for different size necks, and the available size in this record is Extra Small with a 12mm (1/2") width and a 20-32cm (8-13") length range.
If your cat's neck measurement falls outside that range, the collar is not the right fit, no matter how you adjust it. Do not guess or stretch the sizing. Use the measurement as your first checkpoint.
Fitting the collar in four checkpoints
- Measure and compare: Measure your cat's neck circumference where the collar sits and check it against the 20-32cm (8-13") length range for the Extra Small size. This is the only size listed in the supplied record.
- Adjust the webbing: Slide the adjustable webbing so the collar sits snugly but not tightly. The manufacturer states to allow a finger gap between the collar and neck for comfort. Use that as your fit check.
- Check the safety release: The Fish Clip safety-release is designed to release at 2kg to prevent snagged cats getting stuck. Make sure the clip is fully closed and sitting flat against your cat's neck, not twisted.
- Attach ID and bell: The stainless steel K-ring is for an ID tag, and the warning bell is included for wildlife protection. Check that the bell rings freely and the tag hangs without catching on the webbing.
What the Red Dingo Fish Bone collar provides
- Red Dingo Cat Collar Fish Bone Dark Blue: Safety-release Fish Clip designed to release at 2kg to prevent snagged cats getting stuck. This is the core safety feature: if the collar catches on a branch or fence, the clip should open under that load rather than trapping your cat.

Red Dingo Cat Collar Fish Bone Dark Blue - Red Dingo Cat Collar Fish Bone Dark Blue: Length adjustable for different size necks, with a 20-32cm (8-13") length range and 12mm (1/2") width for the Extra Small size. The adjustment range tells you whether your cat's neck measurement fits this collar before you try to put it on.
- Red Dingo Cat Collar Fish Bone Dark Blue: Includes a warning bell for wildlife protection and stainless steel K-ring for an ID tag. The bell gives birds and small wildlife advance warning, and the K-ring keeps identification attached without adding a separate collar.
The finger-gap check is your daily safety test
After fitting, slide one finger between the collar and your cat's neck. The manufacturer specifies allowing a finger gap for comfort. If you cannot fit a finger, the collar is too tight; if two fingers slide in easily, it is probably too loose and may slip over the head or catch more often.
Check this gap weekly, especially on growing kittens or cats that wear the collar continuously. A collar that was correctly fitted can loosen over time as the webbing settles.
Why the 2kg release matters for a quick-release collar
The Fish Clip is designed to release at 2kg. That is the load at which the safety release should open to free a snagged cat. It is not a weight limit for your cat. The 2kg figure describes the force on the clip, not the size of the animal wearing it.
Because this is a quick-release collar, it will also come off if your cat pulls hard during play or a scuffle. That is normal. Check the collar after any outdoor session and reattach it if the clip has opened.
Cat collar safety checklist before you head out
Run through these checks each time you put the collar on or let your cat outside.
- Neck measurement still matches: Confirm the collar still sits within the 20-32cm (8-13") range and has not been adjusted past the webbing limit.
- Finger gap present: One finger should slide comfortably between the collar and neck.
- Safety clip closed and flat: The Fish Clip should be fully engaged, not partially open or twisted.
- Bell rings freely: The warning bell should move and sound when your cat walks, not be stuck against the webbing.
- ID tag secure on the K-ring: The stainless steel K-ring should hold the tag without the ring bending or the tag catching on the clip.
What the supplied information does not cover
The record does not include cleaning instructions for this collar. If it gets dirty, check the product label or packaging for the manufacturer's recommended cleaning method rather than guessing. The record also lists only the Extra Small size, so if your cat's neck is larger than the stated range, this specific collar may not be suitable.
No other sizes are confirmed in the supplied information, so do not assume a larger size exists without checking the store listing.
