CCL, I’m so sorry you got hurt. Any change, especially moving is stressful to a cat.
I can only imagine how much more stressful it would be for a blind kitty.
Sometimes they lash out in fear or if over stimulated.
Phoenix, much like Ripley used to attack me when he was in a bad mood.
I could barley touch him without getting bit or scratched.

Paddy bear is so adorable and he looks so happy being brushed.
I can only brush Phoenix around his neck. Any other places I get to feel his lethal claws.
I wish you the best of luck. I’m sure this little guy is going to be a real sweetheart.
