My husband found 5 newborn kittens 9 weeks ago in our backyard and the mother was dead not too far away. They still had their umbilical cords attached, so just a few hours old. I have been taking care of them full time myself, but one declined and died at 8 days old, another one had a funny looking head, was the smallest, and had what seemed like seizures, and he died at 4 weeks old along with another kitten. In the morning they were all fine, and by lunch time two were dead, so that left me with 2. These two have been doing wonderful, but the male will not stop eating or drinking so I have to end up taking away the food from him because his tummy gets huge. Tonight we went out to dinner and came back and he was in the kennel with all his hair sticking up, arched back, and growling and spitting and swatting at his sister, and he made 2 poops outside the litter pan. She desperately want out of the kennel, and every time she approaches him, he arches his back and growls at her. What is going on with my kitten?
