For a blinking animal (or anything else) start by making a drawing of something (I did a quick drawing of a dog). Save the picture to your computer then continue.
Erase the eye, and replace it with a black line. Also save this picture to your computer.
Then, you put the pictures together in a movie (Windows Live Movie Maker, makes it easy). Make sure that you make the picture with the eye closed, not stay on screen as long as the other one (otherwise it will look like it is about to fall asleep instead of blinking).
Now for the opening mouth things (or talking). You'll start off like we did in the first one, just make something (remember to save each picture to the computer).
Then, erase the bottom jaw and draw an opened mouth. Then save it to your computer.
Then put the two pictures together as a movie and once again, it is best to make the picture with the cat's mouth opened to stay up shorter. If you have any questions about anything, just leave a comment.
