In brief: Interesting
First off one needs to understand that a positive skin test or blood test does not mean one is allergic to that allergen.
It simply means there is a positive test. Additionally, the size of the skin test or the degree of positivity of a blood test does not quantify the severity of one's allergy. The patients clinical symptoms and history dictate what is clinically significant allergy.

In brief: Non unusual
Many people may be allergic to a species of animal (dog, cat, bird) but have no reaction to the family pet.
The allergy is to the animal saliva, and not to the fur or dander. By being constantly exposed to the unique saliva of that particular animal the allergic response is diminished - their immune system no longer reacts to that one. However other animals will still cause an allergic reaction.

In brief: Repeat the test
Very unusual and i would repeat the test.
Also the type of cat may make a difference.
