For me i prefer cats , Cat is better than dogs.. but dog is also good dog is the best for security alerts and dogs can be your friend. But dog is not good all the time, sometimes dog can kill you if a dog has a rabbies your life will risk.. Thats why i prefer cat , for me cat is the best stress reliever.. my cat is so cute, even im hungry and tired when im with my cat i feel so happy and comfortable , also cat can play with you and you cannot die even your cat bite you. cat is the best for stress reliever and dog is the best for security alert.. both dog and cat are the best . But cat is playful and agile, cats love to play. They are quite acrobatic too, especialy when you take out a toy fishing pole or a cat dancer toy. They will reap , run and pounce on the toy, which is great fun to watch.
