I understand the context but the animation wasn’t explaining much “why” they were fighting :) I do get it, cats are assholes! But it would have been nice to see the first one.
Some frames are jumpy, missing colouring and it would have been better if you uploaded it as a video with a pause/play button! If you export the video into .swf, use swivel to convert it! Good quality and it even allows you to make a watermark on your video (if you want your logo and so on) created by Newgrounds

otherwise, good job and keep on animating (Y)
