I got a non-dog savvy cat and had a non-cat savvy dog...so I posted here and got lots of GREAT advice.
Heres my thread:

We put a gate across a room, put her litter box and food in there...so she had a safe place to go and when she was ready she came out and investigated. Zoey whacked Elmo once (on her own terms, we werent holding her) and then it was all over. Elmo respected her and let her be. I dont allow chasing of cats and I didnt allow her to beat up Elmo (she lives with my ex now).
