Abstract
A novel swivel tethering system for attaching to a cage of a laboratory animal is disclosed which provides a greater degree of mobility for laboratory animals. This tethering system provides for extended lateral movement which is not limited to the tether length and is ideally suited for chronic indwelling catheterization since it can minimize the stress created in the animals caused by a limited tether length, thereby reducing the potential distortion of blood parameters.
