Hi Woodsman,
I agree with your interpretation but maybe this dream is a warning about a specific incident and specific people in the near future who will do or attempt to do what you described in your interpretation. Remember, if it is not about spiritual matters then it is about normal or natural matters. In such case, the cat is about being rebellious toward you personally and then it has nothing to do with God. In such a case the dog is a personal attack. Dogs do not always symbolize backsliding, it sometimes symbolizes a vicious attack of violence.
