I, I think one of the biggest changes is, well, the, probably the biggest change is a result of the fact that we’ve got more access to animals back not long before I started there, there weren’t very good anesthetics if, if all you had was ether and barbiturates, you had to have the animal in hand and put a mask over their face or get an iv. And so the development of zoo medicine really came hand in hand with the ability to safely anesthetize animals and, and get our hands on them. So, so that has changed a great deal during the time that, that I’ve been a zoo veterinarian.
