What does a tether system do?

• A. Allows for restraint of an animal for one-time access
• B. Allows for repeated vascular access without the need to restrain or anesthetize the animal each time
• C. Allows for repeated vascular access without the need to restrain, although anesthetizing is still required each time
• D. Allows animals to be restrained in order to prevent biting of personnel

Answer: (B)

A tether system enables repeated vascular access without restraining or anesthetizing the animal each time. It uses an implanted catheter connected to a flexible tether and swivel that exits the cage, so the animal can move while the line stays in place. This setup allows blood draws or drug administration to be performed multiple times without handling the animal extensively, which reduces stress, minimizes anesthesia exposure, and helps maintain catheter patency for longitudinal studies. It’s not about restraining the animal for a one-time access, nor does it require anesthesia for each access, and it isn’t primarily a bite-prevention device.
