Wow, that is really disturbing that a vet is recommending this surgery. I know that some vets will consider it if a client is requesting it and many will not do the surgery at all but to actually be the one suggesting the surgery to clients and for such a ridiculous reason is unbelievable. People have been living along side cats for a long, long time and their safety shouldn't be compromised if they are not mistreating the cat. Normal, healthy cats don't just claw people without reason and if they do, there would probably be some underlying cause that needs to be looked at.
I'm so shocked that a vet is suggesting this surgery and I wonder how many families he is suggesting this to and how many cats are going through this procedure at his clinic for what can only be motivated by financial gain for this guy as there is no other practical reason. Maybe the Veterinary Medical Association should know about him and his hospital.
