Cat guardians encounter labels that mention CBD, hemp seed oil, isolate, and broad-spectrum. The terms often appear together and can be confusing. This article explains CBD product basics for cats in Australia in plain language. It focuses on label literacy, the meaning of mg/mL, and how to read a COA (Certificate of Analysis) from an independent lab. It also shows how oils compare with treats for everyday practicality. No dosing, no medical or legal claims—just neutral steps to interpret packaging and documents with confidence.
What CBD is for Cats
CBD (cannabidiol) is one of many cannabinoids found in cannabis plants. Pet CBD products are made by extracting cannabinoids from flowers and leaves and dissolving the extract into a carrier oil. That makes them different from culinary seed oils. Hemp seed oil is pressed from seeds and typically contains negligible cannabinoids. If a label lists both “hemp seed oil” and a CBD content, the product is a CBD oil using hemp seed oil as the carrier.
Labels commonly refer to extract type. The extract type is not a quality score; it simply describes composition.
- Isolate: refined CBD with non-detectable THC and minimal other cannabinoids.
- Broad-spectrum: CBD plus selected non-THC cannabinoids and terpenes; THC is typically removed to below detection.
- Full-spectrum: CBD alongside a broader range of cannabinoids and terpenes; may include trace THC within relevant limits.
Strength on oils appears as mg/mL. mg/mL means milligrams of CBD per millilitre of the finished liquid. Some labels also show total milligrams across the bottle. Strength per millilitre is easier to compare between different bottle sizes. Treats and chews use milligrams of CBD per piece.
Carriers influence texture and taste. Common carriers include MCT oil (neutral, thin), hemp seed oil (nutty aroma), and salmon or other fish oils (strong odour, often appealing to some cats and too intense for others). Thin oils disperse easily in food. Thicker oils may cling to droppers and have a more persistent aftertaste. Packaging touches—such as droppers with volume markings—help deliver consistent liquid portions without implying any dosing advice.
Australia’s rules for pet CBD
This section provides a high-level overview only. It does not provide access pathways, prescriptions, or legal guidance.
When a product containing cannabinoids is marketed for animals, it typically sits in a regulatory framework for veterinary chemical products. That framework focuses on safety, quality, and labelling. Cannabidiol used for therapeutic purposes may appear in professional discussions under medicine scheduling terms such as “Schedule 4”. Those terms are included here only to help interpret terminology that might be seen on packaging or in technical documents.
Commercial availability, advertising rules, and policy settings can change. Brands that reference pet CBD in Australia are expected to comply with local restrictions, especially around claims and labelling. Independent quality documentation—such as a batch-linked COA—provides practical information without relying on marketing statements. Testing laboratories often reference accreditation against ISO/IEC 17025 and describe methods and detection limits. The presence of method codes, LOQ/LLOD values, and a named independent lab increases transparency. This article does not direct readers to obtain regulated products or describe access routes.
How to choose cat CBD oil
Selection can be approached as a documentation exercise. Focus on what can be verified on the bottle and in the COA.
Label literacy: what to confirm
- Product name and species context (feline-specific or species-neutral wording).
- Extract type listed as isolate, broad-spectrum, or full-spectrum.
- Strength in mg/mL and bottle volume in mL.
- Ingredients: carrier oil and any flavourings.
- Batch/lot number printed on the label or bottle base.
- Storage statements and a best-before or similar stability note.
COA (Certificate of Analysis): why it matters
A COA links quality data to a specific production run. It enables a match between the bottle and the tested batch. Look for a cannabinoids panel that reports CBD in mg/mL for oils (or mg/g for solids), a complete contaminants panel, method references, and LOQ/LLOD figures. A named independent lab that discloses accreditation (for example, ISO/IEC 17025 scope) increases confidence in the report.
Practical fit for cats
- Palatability: odour and flavour drive acceptance. MCT is neutral; fish oils can help or hinder based on preference.
- Texture: thin oils mix easily with wet foods and are simpler to measure in liquid increments.
- Packaging: droppers with visible graduations or pumps with consistent stroke volumes support repeatability (no dosing advice is provided).
Category examples
- Feline-specific oils: smaller bottles, lighter flavours, mg/mL shown clearly.
- Broad-spectrum or isolate lines: extract type stated; batch-linked COA provided.
- Compounding-only: prepared to order in some professional contexts; documentation varies by supplier.
What to question in labelling
- Strength listed only as total milligrams without mg/mL for an oil.
- Missing batch/lot number or a code that does not appear on the COA.
- COA missing dates, method notes, LOQ/LLOD, or the contaminants panel.
- Marketing that implies medical outcomes or comparisons with prescription medicines.
COA reading checklist
A well-structured COA makes it possible to confirm identity, composition, and cleanliness for a specific batch. The checklist below explains what to look for and where it is usually found in the document.
Identification
- Product name and format (oil, treat, topper).
- Batch/lot number that exactly matches the bottle print.
- Matrix description (oil vs edible vs raw material).
- Dates for sample receipt and analysis.
Cannabinoids panel
- CBD reported in mg/mL for oils or mg/g for solids.
- Other cannabinoids listed with values and method references.
- LOQ/LLOD stated, with any conversions from acid forms to totals explained.
Contaminants panel
- Heavy metals (for example, lead, arsenic, cadmium, mercury) with pass/fail notes.
- Pesticides via a multi-residue screen, with method identifiers.
- Microbiology such as total aerobic count, yeasts and moulds, and pathogen notes where applicable.
- Residual solvents relevant to extraction, with acceptance criteria.
- Optional terpenes profile and calculated totals.
Laboratory and reporting
- Independent lab identity: name, address, or certificate number.
- Accreditation reference such as ISO/IEC 17025 scope note.
- Methods and validation notes with analyst signature or a digital seal.
- Pass/fail summary that consolidates key outcomes.
Matching the batch

Oils vs treats comparison
Both formats can be found in pet-labelled cannabinoid products. The main differences are how strength appears and how the product is portioned. Oils present strength as mg/mL and allow small liquid increments. Treats show milligrams per piece and are pre-portioned. Acceptance depends on odour, texture, and eating habits rather than format alone.
| Form factor | Extract type | Flavour/base | Strength display | Portion control | Typical carriers/ingredients | Notes for cats |
|---|---|---|---|---|---|---|
| Oil (dropper bottle) | Isolate | MCT (neutral) | mg/mL | Fine liquid increments | MCT | Neutral odour; mixes with wet food |
| Oil (dropper bottle) | Broad-spectrum | Hemp seed oil | mg/mL | Fine liquid increments | Hemp seed oil | Nutty aroma; check clarity |
| Oil (dropper bottle) | Full-spectrum | Salmon oil | mg/mL | Fine liquid increments | Salmon oil | Strong odour; may help or hinder acceptance |
| Oil (pump) | Broad-spectrum | MCT + flavour | mg/mL | Medium control; fixed pump stroke | MCT, natural flavour | Convenient; confirm pump consistency |
| Soft chew/treat | Isolate | Chicken or fish flavour | mg per piece | Pre-set; split by piece | Starch, glycerine, flavours | Texture-sensitive; some cats reject chews |
| Crunchy treat | Broad-spectrum | Meat meal flavour | mg per piece | Pre-set | Grains, binders, flavours | Crisp texture; odour is decisive |
| Topper powder | Isolate | Palatant powder | mg per scoop | Scoop-based | Palatants, carriers | Sprinkle-on; check even mixing |
| Gel/paste | Isolate | Oil/gel base | mg per marked line | Line-based | Oils, emulsifiers | Useful if droppers are difficult |
Storage & handling
- Keep the cap closed tightly to limit air exposure.
- Store in a cool, dry place away from direct light. Refrigeration is product-dependent.
- Wipe the dropper before returning it to the bottle to minimise contamination.
- Do not decant into unlabelled or reactive containers.
- Watch for noticeable changes in colour, odour, or texture.
- Follow the printed best-before statement on the carton or label.
Practical evaluation workflow
- Front-label scan: extract type and strength in mg/mL for oils; mg per piece for treats.
- Ingredients: note carrier and flavour; consider palatability for a picky cat.
- Batch/lot code: locate the batch/lot number on the bottle or box; record it.
- COA access: scan a QR code or visit the brand’s batch results page.
- Open the COA: verify product name, format, and batch/lot number match the bottle.
- Cannabinoids: confirm CBD appears in mg/mL with a clear method and LOQ/LLOD.
- Contaminants panel: check heavy metals, pesticides, microbiology, and residual solvents; read pass/fail notes.
- Laboratory: confirm an independent lab identity and any ISO/IEC 17025 note.
- Packaging check: intact seal and cap; dropper or pump works consistently.
- Record-keeping: save the COA and note the batch/lot number for future reference.
Myths & reality
Myth: Hemp seed oil equals CBD oil.
Reality: Hemp seed oil is a culinary carrier pressed from seeds and typically lacks cannabinoids. A CBD oil contains a cannabinoid extract dissolved in a carrier, which can include hemp seed oil.
Myth: A higher percentage on the label is always better.
Reality: Percentages can be unclear. Strength expressed as mg/mL shows how much CBD is present per millilitre, making comparisons easier across bottle sizes.
Myth: A COA is optional.
Reality: A COA links test results to a specific batch/lot number and includes a contaminants panel. It is the most practical document for verifying what is in the bottle.
Myth: All third-party labs are the same.
Reality: An independent lab that discloses methods, LOQ/LLOD, and accreditation (for example, ISO/IEC 17025) adds transparency.

FAQs
Is CBD oil the same as hemp seed oil for cats?
No. Hemp seed oil is pressed from seeds and typically contains negligible cannabinoids. CBD oil contains a cannabinoid extract dissolved in a carrier such as MCT, hemp seed oil, or salmon oil.
What does mg/mL mean on cat CBD labels?
mg/mL states how many milligrams of CBD are present in each millilitre of the liquid. It expresses strength and helps compare products with different bottle sizes.
What is a COA and why does it matter?
A COA (Certificate of Analysis) is a laboratory report for a specific batch/lot number. It lists the cannabinoid profile and a contaminants panel. It also identifies the independent lab and methods used.
What should be in the contaminants panel?
A well-rounded panel covers heavy metals, a pesticides screen, microbiology, and residual solvents. Some reports also include terpenes as optional information.
How do I match the batch/lot number to the COA?
The alphanumeric code on the bottle should appear in the COA header. Product name, format, and strength should also align. If any details differ, contact the manufacturer for clarification.
What is the difference between isolate and broad-spectrum for cats?
Isolate contains refined CBD with non-detectable THC and minimal other cannabinoids. Broad-spectrum includes CBD with selected non-THC cannabinoids and terpenes, with THC typically removed to below detection.
What’s the role of an independent lab and ISO/IEC 17025?
An independent lab reduces conflicts of interest. Accreditation such as ISO/IEC 17025 indicates that methods and quality systems have been assessed against an international standard.
Are oils or treats easier to portion for cats?
Oils show strength as mg/mL and allow small liquid increments. Treats list milligrams per piece and are pre-portioned. The easier option depends on acceptance, texture, and whether a cat eats the full portion promptly.
Can a product say “hemp seed oil” and list CBD content?
Yes. That means the CBD extract is dissolved in hemp seed oil as the carrier. The product is a CBD oil with a hemp-seed carrier, not a plain culinary seed oil.
Where is strength shown for treats vs oils?
Treats show milligrams per piece. Oils show mg/mL. Both should be confirmed against the COA cannabinoids panel.
