Effective sedation of rabbits, guinea pigs, rats and mice with a mixture of fentanyl and droperidol.

A minimun effective dose rate for Innovar-vet was established for producing sedation of rabbits, guinea pigs, rats and mice. The level of sedation permitted a minimum of restraint and abolished painreactions. No special precautions were necessary and administration was by simple intra-muscular injection. Recovery occurred within 1-2 hours and was uneventful and without excitement. A single operator was able to carry out bleeding safely, and would be able to carry out other minor procedures with minimal stress to the animal.
