How long have you had Easy? We had gotten a dog for a while that my cat hated and she hated my cat. The dog would hunt my cat to tease her and my cat would yowl, hiss, spit, etc.. It took about 2 weeks of them fighting and yelping until my dog learned that my cat was the boss. Every once and a while they would fight just for fun, but they really got along. By the time we adopted the dog out, they were sleeping in the same little bed with each other and kissing on each other. I think it just takes time and you just have to let them work it out.
