Q. I am 25 years old and live with my 4-year-old cat, Hannah.  She is a longhaired black tortie and has always been in great health. I am familiar with iridology. I'm not sure if this pertains to Hannah, but lately I noticed brown spots appearing in the iris of her right eye. She doesn't have any other symptoms, and when I ask her telepathically, she says she feels wonderful. Do you know what the spots could be, and how do I go about getting her medical help? 

A. Many calico cats have changes in their iris (color), which is reflective of their coat color. I suspect that is what's happening to Hannah. Still, I would have her eyes examined by a veterinarian, preferably a veterinary ophthalmologist, just to be certain that these changes are benign. Some heavily pigmented cats can develop a tumor called a melanoma in their iris. This disease must be dealt with surgically. At this point, blood tests will not tell you anything regarding her eye. Good luck.
