Our male cat not only acts like a dog but spends more time with our two dogs than he does with the other two cats. Our house is divided by a series of gates to keep the cats safe. He is the only one who walks between both areas. In fact he sleeps in our room with the dogs. Whenever/wherever the two dogs come together he is soon right there too. Grooming the dogs and he wants to be groomed. We have a treat routine for the dogs in the morning before we leave for work and he has started to insert himself in that too. What makes this cat so adaptable to living with the dogs when his sister is totally afraid of them?
