The secret of Black cat

Week before my Ulcer strike, my cats keep away from me. I don't know how they interpret my health. But, I still remember 1994 when my cat name Miming react before I got a serious Ovarian Operation. My family almost lost me. Month before the incident, he avoided me and stay away from home. Right after my recovery, he returned.
My mother once told me that it is very dangerous to adopt a black cat because they so sensitive about the health of their master. Now a days i observed the same to my black cat named " Intman". She never missed a day for having me at night. I found out that she still stay with me but prefer to sleep on top of my cabinet. When I got sick and still refused to sleep with me, I remember the incident of my older cat. I noticed her unusual action. She always sleep and never play with the other cats. As if she was worrying for something.
the belief on adopting black cat according to my mother has serious explanation. The two incidents seems to prove to me that black cat has secret. There is another beliefs related to a black cat..." When it crosses on the road before a journey give a bad signal of accident". This beliefs were believed by the majority.
