another pet, new kitten

There is a new member in my pet family, a sweet little coon cat. As tiny as he is he can do all the things grown cats do, spit and arch his back, and sing. He can move pretty fast and can climb my pant leg and stay in my lap until I have to get up. My other cat Tippy, won't come in the house. As soon as he sees the kitten he hisses and runs away. Mira on the other hand is friendly with the kitten. I haven't named him yet. He is a little love bug.
