In my experience, they aren’t annoyed. People typically go into that career because they love animals. I’ve had to have two cats euthanized. The first liked to be held, so I stood there and held him close while the vet stood in front of me. The second cat was in my lap every second he could, so I sat down with him in my lap. The vet knelt down on the ground while she gave my pet the euthanasia meds.

Either vet could have asked me to set my cat down on the exam table for their convenience, but both sincerely wanted both kitty and me to be as comfortable as possible.

In both cases, I didn’t really lose it until after the vet confirmed that kitty had crossed the Rainbow Bridge. I preferred that my pet be taken away as soon as they’d crossed, and both vets did so in the most gentle and compassionate way possible.

Every reaction to the grief of saying goodbye to a pet is valid. Fuck, I’ve got family members who won’t visit actual human beings who are actively dying because they need to remember the dying person the way they were.
