Answers:    It didn't come across to cause any discomfort to my cats when I took them in for their annual vaccinations a few weeks ago. They be more distressed by having to be put in their carriers and haul off in the car. The shot be nothing compared to that.
It seems like mine hurt me more than the cats' shots hurt them. Agree near the other answer, they hate the car more, and the smell of the vet's office.
