PROMPT: While recovering from everything to do with Grindlewald, Percival Graves is adopted by a cat. It is the ugliest, most beat-up looking cat you've ever seen and it absolutely hates everyone but Percival.

People think it's a Kneazle or an animagus or somehow magical or something but no, it's just a rough-life alley cat that wandered into Percival's house and never left.
