I wish I knew what the magic was with the Bubbles-Mango-Peaches happy household. Bubs wasn't crazy about Mango when he arrived but quickly grew to love him. Peaches joined the household a year later and, again, Bubs wasn't the least bit happy but Mango quickly welcomed her. Now Bubbles and Peaches are great friends too. My best assesment is that Mango is such an even-tempered, happy little guy that he's the glue that holds eveything together. He is the Alpha Cat and, at times, the girls compete for his attention.
