Mark,
This is more of an Arff than a Woof. This is Petey, our rescue schnauzer who we adopted when he was 5. He was blind with cataracts in both eyes but with the help of the rescue league, the lens in his right eye was replaced giving him 80% vision in that eye and about 50% vision in the left eye. He watches Rin Tin Tin movies with me so I guess he likes silents. Petey turns 12 in August.
In the Woof category, this is Cooper, a lab that my son adopted from a rescue league. Since adoption he's developed a cataract in his right eye and sees almost nothing out of it.
As for Meow, this is Sheema. a torti that my other son adopted from the local animal shelter. She has no health problems so far but we have no idea what a $1200 breed of cat was doing in a shelter.
They all get together from time to time and get along just fine.
Bob
