Our cat recently had a cardiac arrest and, as a result of the brain damage, is totally blind (he may get it back, if not fully, partially). Two days later he is out of hospital and back at home. He also requires a special diet and monitoring of his urine output. We have two other cats in the house, so it's important he is the only cat that has access to his litter tray. We also have balconies that would kill a cat if they fell from them. In the past he and the other cats were fine walking on the balconies.

What tips are there to help a suddenly blind cat adapt to his environment?
