Question
I recently rescued a cat after it was hit by a car. The cat was put under
anesthesia (induction with ketamine and valium, maintained on isoflurone,
given torbugesic as a premed and Buprenorphine for pain).   However,
afterwards, we realized the cat was pregnant, and we guess that she is 6-7
weeks into term. Will the drugs used have any harmful or negative effects
on the kittens?  

Answer
The only thing in that anesthetic/pain management event that might be a problem is the isoflurane, because if is so fat soluble and could get into the kittens. I think that it would be a minimal effect.  The major effect on the kittens would be from the trauma of being hit by a car.
