HI there, This is Kitt
I am no specialist in allergies but "cat" is the red flag I see along with the stress. Also you might ask your Physician for a Medrol Dose pack to try to see if the hives go away. If it is the cat then you have a problem. My daughter is allergic to cats and cannot touch them. They can be around but it is the contact that causes her to break out.
I hope you get to the bottom of your hives quickly.
