For injecting captured animals through apertures of cages.
Cage Injectors (aka mini-skinny jabsticks) are nice and thin, and safe and simple, for injecting captured animals in cages.
A 1m x 3 mL and a shorter 50 cm x 1 mL model are available. They come with 3 spare B-D syringes with the luer-lock nozzles.
The 3 mL version has a locking ridge to prevent the syringe barrel being dragged off on withdrawal.
