Thanks for your comments, I appreciate that.
I originally printed in ABS, since that's how I started printing. There is no issue with printing in PLA. As a matter of fact i now print in ABS and PLA for the same model, just depending on what color I need.
Be aware, the cat needs a lot of filament. I made him hollow to try and save print time and filament. At the time, my wife wanted the cat as big as my FlashForge could print, therefore the larger size.
As for Winnie, my models do not need to be painted, or if you do paint, the pieces are separate to make painting easier.
Personally, I'd suggest you start with Kermit. He is reasonably quick and is an all around favorite. I just got my Prusa for Xmas and it's a great machine, enjoy.
