How would I gradually increase the size of an image?

Each object will increase in size by 5 (height and width). I'm working from the World class. For example, 1st object will be 5x5, 2nd object10x10, 3rd object 15x15, etc. I'm also trying to create a while loop. 
private void setup ()
{

while (i < 25)
      {
       Cat cat = new Cat();
       addObject(cat, 100+15*i, 200);
       i++;
      }
}
I think the code to scale is: 
GreenfootImage image = new GreenfootImage;
 image.scale(image.getWidth(), image.getHeight());
 setImage(image);
I don't know how to reference the cat class, though. I'm a beginner.

private void setup()
{
    for (int i=0; i<25; i++)
    {
        Cat cat = new Cat();
        addObject(cat, 100+15*i, 200);
        GreenfootImage image = cat.getImage();
        image.scale(image.getWidth()+i*5, image.getHeight()+i*5);
        cat.setImage(image);
    }
}
I think this should do this. But I guess that the last objects will be pretty huge and overlap each other.

Line 9 is not needed as the image is already set to the actor. Line 8 does not quite do what Astralman asked for, which is more like 
image.scale((1+i)*5, (1+i)*5);
As far as overlapping, even with the change in scaling provided here (which would produce much smaller images to start with), by the time the counter gets to 3, they will start overlapping; and the last one created will hide all created before it from where the counter was 6 or 7.
