Don't Spike and Li'l Bit look like they are brothers, or father and son? They are not related at all. I suppose they are a common "household cat". But to us they are very individual, unique personalities. I love to see cats loving on each other (Li'l Bit is laying between Spike's back legs). People say that cats aren't as social as dogs, but I beg to differ. They are just sociable, when they choose to be, on their terms. I think I relate to that. Spike will be one in November, and he is larger than our others adult cats. Li'l Bit is still up for adoption. He has become less fearful of people, and purrs very loudly. He has the prettiest little face.
