You are at your job as a VA, checking in on a 15-year-old-cat, Binky. Binky has been vomiting for the past few days. However, he is still interested in eating food, and is having regular, normal bowel movements. You continue to take Binky's medical history, and start to take his temperature. Binky's 'mom', Mrs. Angelis, gets upset and says "Why are you doing that? He doesn't have a fever! He doesn't need that. All you are doing is making him uncomfortable! He hates coming to this place enough as it is!". What do you do?
