"Taking the cat's weight and temperature is not necessary" one vet I visited at the evening clinic said to me. "Taking weight is a waste of time."
I had said that the dog's weight and temperature must be recorded before vaccination. This vet jabbed the cat at the scruff of the neck with the cat vaccine one week before spaying.
"The weight is important," I said. "If the cat loses weight, you can compared to his original weight of first visit. It is not only for litigation or complaint investigation."
Even the hamster's weight must be taken but sometimes I noted that my assistant did not do so.
