"Usually in the morning and at bedtime, my cat’s pupils enlarge enormously, even when there is a bright source of light. She cannot seem to see me either. At the same time, her hearing seems impaired. She calls for me and I have to speak/call loudly, wave my hand/fingers to get her attention to my location. During the day, her pupils seem normal and her hearing as well, although her condition sometimes appears and disappears quickly. I’ve checked her ears; they appear clean."
