They're definitely not friends yet, all Chloe's fault. The boys are totally fine with her, but it's very apparent that she is an Alpha cat, and she hisses and swats at them, even though the smallest -- Robocat, is more than twice her size. I'm sure that things will be fine eventually, it's only been two weeks. It should work out fine in the end. Floppy is the "official" Alpha, but when Daisy was here, she was also the smallest, and whenever she wanted to , she could floor any of her sons without even breaking a sweat.
Yes, it's really good to have 4 cats again. She can't replace precious Daisy, but it's so good already to have a girl cat in the mix again! She definitely adds that special dynamic that was missing since Daisy left us.
