This is a cute crochet mouse toy filled with catnip. It is a quick project and great for beginners. The stitch is tight so it is hard for cats to rip apart (at least mine hasn't so far!). I used Vanna's Choice yarn and a size G/6 hook. The pattern can be found here (you might have to register to get the pattern but its free and there are lots of other great patterns there too). This is a good pattern to start with if you are just starting with crochet amigurumi. Give it a try!
