Here are two videos showing how vets and veterinary staff deal with angry cats in their care.
The interesting aspect of these instructional videos is that the first is using a real patient and the second uses role play (and well done to the guy playing the cat!).
I can’t watch the first video because it upsets me to see cats so distressed. I’d make a terrible veterinarian. Maybe not, but I don’t like these videos because I can sense how upset, distressed and probably in pain these cats are.
TURN THE VOLUME DOWN FIRST.
I found the second video amusing and instructional. It is probably a better video on that basis.
