Grace, I'm so sorry about Grady. I've had no experience with injuries such as this, but do you have a small room you can keep him in instead of a cage?

Some kitties, just hate to be caged. I had renos done to my condo last November and I had to cage Max. When I came home from work, I couldn't believe what I saw and it took me at least an hour to clean up the mess.

Hugs to you and prayers for Grady. I'm sure other Pet Talkers will have some great suggestions for you.
