CCL,
I am so sorry about your wrist. I know how painful a cat bite is, and really, how dangerous it can be. I would make sure you are keeping it iced and elevated, until you see how severe it is going to be. I, too, would hesitate to go to the ER.

As to Mr. Magoo, I say this gently, but....it isn't his fault. Too much, too soon. It has been a really traumatic ride for him. You are to be hugged so hard for your efforts, but, what Mr. Magoo really 'needs' is to be left alone, to acclimate.

I would leave him be, and interact with him enough for daily contact, but, do not involve the other guys. Let him get used to you and your husband and his environment. My guess would be that last night he was too shocked to do much of anything, but now that he has a slight lay of the land...well, his defenses are coming out.

Please do not lose hope over this incident. Look at this as a learning experience.

I am so sorry about your wrist, and I imagine, Mr. Magoo is not happy that he had to lash out like that.
Johanna
