What was your source for this sewing project?

I really like that I added a doorbell. Every time one of the cats goes into (or comes out of) the house, the bell will rinkle, making the other cat curious. The house has been the reason for many fights, even some heated paw fights through the window (lol), but they mostly love laying in it :). What advice would you give someone starting this project? This project involves sewing through very thick layers, which is definitely tricky, but not impossible! My cat house is much bigger than the tutorial, because my cats are much bigger than the average cat.
