What an eye-opening article. Knowledge is power indeed. Imagine how much a cat can suffer if the owner is not empowered with this kind of information. I had no idea that cats can go blind especially due to hypertension. They more or less show the same symptoms as humans. It’s encouraging to learn that there are interventions in place if the symptoms are detected early.

I can’t begin to imagine the suffering that the cat could go through if neglected to the point that it goes blind. It’s hard already for human beings. I am really empowered by reading your articles. The first time I learned that cats also suffer from hepatitis was through one of your articles. Though I’m not the owner yet I’ve learned so much. I’ve come to realize that cats need the same care that we give human beings and they need love too. Should I decide to own a cat at least I’ll have gathered sufficient information about on to take care of them. Thank you for your informative articles. I really do enjoy reading them.
