I got two female kittens (named Penny and Miracle)from a family friend about a year and 3 months ago. When we took the two darlings home, they got along just fine. They would cuddle at night and play during the day. As they grew up, they stopped cuddling so much and grew apart. Penny became for dominant and Miracle more shy and timid. Whenever Penny isn't around, Miracle becomes active, but as long as her sister is around, she doesn't. There isn't any fighting and they can sit next to each other, but no more cuddling. They both have separate food bowls and litter boxes. Please help my kitties!
