One of my cats eyes is red throughout his whole eye. He was not born with it. It started when he was about a year old with just spots of red and as he grew older it got worse. The red now covers his whole eye except for his pupil, he is now 5 years old. The eye doesn't seem to bother him at all...
I have two tabby cats. I have had them both since they were kittens, one is 5 years old and the other is 3. They get a long good with each other, except for the occasional cat fight which can get pretty loud sometimes but they don't hurt each other. I have never had a problem with feeding them...
