Dog people, thank you for your patience. I know so little about life with dogs;our Bailey grew up with Abby and there was never a problem between her and the cats. What's happening now leaves me clueless as to what to do. Mo is charging at the cats. This has happened once before and we thought perhaps she was startled.. but just now, Jean Claude and Rhett were sort of moving fast and coming from the dining room, and Mo shot off the couch like a rocket, coming right at them.Jean Claude made a panicked exit back to the garage, but what was most surprising was Mr. Rhett's reaction! He puffed up and with a steely gaze , opened up a can of kitty whoop *** ,did the best John Wayne swagger I've ever seen and came after Miss Mo! I had to call him off and gave Mo a firm "no". Jean Claude is only slightly traumatized and Mo is back on the couch with my daughter, looking a bit guilty. I'm sure there are ways to solve the problem, but I feel so badly for my sweet little Jean Claude. He's my feral baby and my daughter and I are the only two humans he's not terrified of.He's easily frightened and so confused by the new sister. Any advice would be greatly appreciated.
