Wildlife Feeding Tube Size Guide
Wildlife Feeding Tube Size Guide
Choosing a wildlife feeding tube starts with understanding the measurements used to describe tube size. The Peculiar Purple Possum’s Lumenline collection is designed for trained wildlife rehabilitators and veterinary professionals who need small, clearly differentiated feeding-tube sizes.
Understanding feeding tube measurements
French size (Fr) describes the outside diameter of a tube. As the French size increases, the tube becomes larger in diameter. Diameter in millimeters gives the corresponding physical width. Gauge is another size reference that may appear alongside French size.
Tube selection should be based on the individual animal’s anatomy and species-specific guidance rather than age or weight alone. A tube that is too small can restrict formula flow, while a tube that is too large can cause injury. When there is any uncertainty, obtain guidance from an experienced wildlife rehabilitator or veterinarian before feeding.

Single-lumen and multi-lumen tubes
Most Lumenline sizes use single-lumen construction. Size 8 is offered in a multi-lumen configuration for trained rehabilitators working with larger animals, including armadillos. Always use the construction and diameter appropriate for the animal and the guidance you are following.
Why closely spaced sizes matter
Very small differences in diameter can be meaningful when working with tiny wildlife. Lumenline’s graduated size range provides smaller steps between tube diameters so trained rehabilitators can select a more appropriate size for the individual animal instead of relying on a one-size-fits-most approach.
