When Maisey had a growth removed from her upper left sinuses the vets didn't send any meds home for her. She was totally freaking from the cone to keep her from pulling out stitches. I went back to the vets and called them twice, but they refused to give any meds for her. I finally got the hydrocodone that was left from my infant grandson's hernia surgery when he was 9 lbs. Maisey weighed 10 at the time and I gave her a dose. She & I slept fine, cuddled up for the night. When I told the vets the next day they went BALLISTIC. I told them it was their fault for not giving me something when I begged 3 times. They said at that time that they could find nothing in the literature about it and cats. I said I didn't care. Maisey was so totally FREAKED that She and I would have rather had a peaceful end than what she was going through. Needless to say she is fine four years later.
