About Brushtail
Brushtail refers to meat from the common brushtail possum (Trichosurus vulpecula), an exotic protein sometimes used in novel-protein pet food formulas.
Brushtail, typically referring to brushtail possum meat, is used in pet foods as a novel, generally lean animal-protein source that supplies high-quality amino acids and can be useful in limited-ingredient or elimination diets for dogs and cats. It may help pets with common meat sensitivities, but availability and palatability can vary, and reputable sourcing plus proper processing are important to ensure safety and comply with any local wildlife or regulatory considerations.
- Derived from
- common brushtail possum (Trichosurus vulpecula)
- Primary role
- exotic novel-protein source for limited-ingredient diets
Why it's used
Brushtail is fed a wild browsing diet of leaves, shoots, and grasses, and is often described as low in fat with a notable omega-3 and omega-6 fatty acid content compared to more common livestock meats. Because most pets have never encountered it before, formulators use it as a novel protein in elimination-style or limited-ingredient recipes intended to avoid previously eaten proteins.
Common concerns
- Wild-sourced supply chain Brushtail is a wild-harvested, invasive-species ingredient in New Zealand rather than a farmed livestock protein, so consistency and traceability depend on the processor's sourcing and handling controls.
- Toxoplasma gondii exposure Marsupials are documented as highly susceptible to Toxoplasma gondii infection, and undercooked wild game meats are recognized in the literature as a route of Toxoplasma exposure.
- Effectiveness as a novel protein depends on prior diet history Veterinary elimination-diet guidance (e.g., Tufts Petfoodology) notes that a protein only works as a true 'novel' option if the individual pet has no history of eating it, so a full dietary history is needed before relying on brushtail for a diet trial.
Also relevant
Novel-protein diets like brushtail-based formulas are one of two main elimination-diet approaches used to investigate suspected food allergies in pets, the other being hydrolyzed-protein diets, and consulting a veterinarian is recommended before using either for diagnostic purposes.
4 sources cited
- Brushtail possum meat is used as a novel exotic protein in commercial pet foods, sourced from wild-harvested New Zealand possums
- Marsupials are remarkably susceptible to developing toxoplasmosis
- Undercooked wild game meat is a recognized route of Toxoplasma gondii exposure
- Novel protein diets (unique protein/carbohydrate sources the pet has not previously eaten) and hydrolyzed diets are the two main categories of elimination diets used to diagnose food allergy, and a good dietary history is essential to selecting a truly novel protein
