I have a grey and white male tuxedo cat named Alex that showed up at the place where I worked nine years ago and adopted me. He has been my little buddy and an only cat for all that time. A couple of days a calico kitten showed up under my porch cold and hungry and very friendly. She is around three months old so I figure someone dumped her. being the softy that I am I took the cat to the vet and brought her inside. I have one problem Alex is not happy about the situation and hisses and growls at me, normally he is a lap cat and very friendly.
