They are probably on sale in the US too, but I don’t know for sure. Here they are regular $19.99 and are on sale for 50% off. They have scarf kits and hat kits with cats, dogs, sheep, and monkeys. The heads, feet, and tails are pre-made and they come with knit or crochet directions. They come in various colors, with the cat in pink, rainbow, or gray.
I got the pink kitty and it took a couple of days to make. Their pattern uses all single crochets and is easy to make, but you can switch out to a different pattern if you want something with a bit more texture.
