My parents “grumpy old cat”. Turns out she was just blind and frightened.

I recently moved in with my parents. They said our old cat was just grumpy and avoided everyone, even though I remember her being very friendly when I was a teenager. It only took me a few days to realize that she could barely see anything. As soon as I started guiding her to her food and announcing my presence whenever I’m near her, she started acting like this to me. I will be doing more research on how to help her.
