A hole at the base of the door allows for the whole tail to be available for tail injections/ sampling, pulse transducer etc. The lateral holes and slots allow for good ventilation and access to the animal. The available space for the animal can easily be adjusted by sliding the doors and fixating with the upper screws. The mouse model has a black nosecone for a less stressful environment while the rat size has transparent doors.
