Here is a cute as anything cat I crocheted from a fab pattern available on the internet at http://www5a.biglobe.ne.jp/~mite/index.html
The original was in Japanese, but the creator has also translated into english!

He was quite easy to make, but I had loads of problems getting plastic pellets for his beany-bum, in the end I used lentils-but these aren't really heavy enough. Later my friend found them on the internet, but I still don't understand why no knitting or haberdashy shops in Edinburgh sell them!
