This is a cat keychain about 7 cm tall, made with a 2 mm hook, plus a crocheted donut that hangs next to it. It is the smallest project on this site and the fastest: head, body, ears, nose, legs and arms together take less than two hours, and the donut takes twenty minutes.
The trick is the scale. At 2 mm, every stitch counts, so the eyes go between rounds 9 and 10 with exactly 6 stitches between them, and the pink inner ears are made separately and sewn on flat. If you work it in thicker yarn you get a small plush instead of a keychain — same pattern, very different object.
Every round is written out below, including the donut and the icing drip.

Slip the icing over the donut and sew it down at the inner edge. Then attach both the cat and the donut to the keychain ring.

Notes
At 2 mm the pieces are small enough that a magnetic stitch marker is worth more than a yarn one. If you want a bigger version, use 3.5 mm and sport weight and the cat comes out around 12 cm, which is a keychain for a bag rather than a key.
For bigger cats, Cucho the Cat is 12 cm in chunky yarn, Little Miki Cat is a hooded 4-inch cat, and Cream and Brown Kitty is a jointed full-size one. Everything is on the patterns page.
Pattern source: cat keychain with donut, as shared by the original designer on the amigurumi pattern blogs.
If you want a bigger cat than the keychain, Esperanza Cat is 24 cm with a 29-round tail.
Another pocket-sized make: Penny, a plush creature closed with slip stitch decreases.
For a cat toy with a purpose, Cat Rattle is a 42-stitch ring with a bell inside and a 34-round handle.
For a bag in cord rather than cotton, Slice Handbag is a 68-stitch oval with short rows for the walls.
