Bair Hugger Veterinary Accessories
A modular system of cage adapters and accessories designed for 3M Bair Hugger forced-air patient warming units. Pass the warming hose through the door of standard recovery cages and floor-to-ceiling cage runs to a 3M warming blanket or gown on the patient, with no pinched hoses or propped-open doors. Every product is designed and tested in a working veterinary clinic.
Whether you call it a Bair Hugger cage adapter, a cage door attachment, a kennel warming port, or a recovery cage passthrough, the job is the same: keep the warming hose connected to a patient while the cage door stays closed and latched. These fit the 3M Bair Hugger Model 675 hose and seat into standard stainless steel cage doors, including Shor-Line systems.

Frequently Asked Questions
What is a Bair Hugger cage adapter?
It is an attachment that creates a sealed port in a closed veterinary cage or kennel door so the Bair Hugger hose can pass through to a 3M warming blanket or gown on the recovery patient inside. It replaces taping the hose through the bars or propping the door open. People also call it a cage door adapter, a cage passthrough, or a kennel warming attachment.
Will these adapters fit my Bair Hugger?
They are sized for the 3M Bair Hugger Model 675 hose, which is the unit they have been fitted and used with. We have not verified other Bair Hugger models or other warming units, so we do not list them as compatible.
Which cages and kennels do they work with?
They seat into the ventilation slot of standard stainless steel veterinary cage and kennel doors, including Shor-Line cage systems. The Runs Extension covers taller floor-to-ceiling cage runs.
Which product do I need?
Start with the Cage Passthrough Adapter for standard recovery cage doors. Add the Cage Runs Extension if you warm large or giant breed patients in floor-to-ceiling runs.
