How to make a rat fat?

How about instead of spending money on all the food you would need you give Gucci to someone she can get all the attention off? Prada already seems to get a lot of your attention wich is great but really they both deserve it. If you can just share the attention the problem might be solved by itself. Also your rat won't notice that you are making her fat because she is 'mean' she will notice that she is getting fat and unhealthy.
