I wanted to share a bit about Cleo for those who haven't read her story. She is a 10-year-old calico who lost her hearing over the last two years. It was a gradual process, but now she doesn't respond to the doorbell or my voice at all. She is very sweet but can be easily startled by sudden movements since she can't hear them coming. I have to be very deliberate with my approach.
We also have Mimi, a 10-year-old black cat who is blind. They get along fine, but the house requires different adaptations for each of them. I know this is a specific niche, but I hope sharing my setup helps others in similar situations.
