He he, why am I not surprised that it is a CALICO who is starting this???

That is a fight not play, but it is the kind you don't need to interrupt. They are just setting boundaries between them. Would be a great "training" vid for new multi cat owners!

I've seen similar in my home many times over the years. I just can't believe someone actually caught it on tape!

I recognized that sound track, whoa! Great one thanks for posting!
