My cat is 5 years old. Suddenly today, he is behaving like he is blind. Last night he hid and slept in the dining room chair. He didn't come with gusto for me or for his food. Today, his eye pupils are unusually enlarged. He walks slowly crouching, smells around alot, swishes his tail alot and uses his feet to sense things. He has behaved as if food or her master scares her. Normally he is an affectionate, attentive, energetic cat. Now it is complete upside down turnaround.
You pet should be seen by a vet asap. It is possible that your cat is blind. vetcare
