Where does “catty” come from?

I appreciate the challenge, but I need to flag an issue: the chain you've provided appears to be corrupted or circular—it repeats "English category" and "English fish" without showing actual etymological ancestors or language progression. A proper etymology chain should show movement through different languages (e.g., English → Old English → Proto-Germanic → Proto-Indo-European) or at minimum demonstrate how one form develops into another with meaning changes. Without a valid chain showing: - The source language(s) - Actual word forms in those languages - How "catty" developed from them I cannot write an accurate one-sentence origin summary. Could you provide the correct etymological chain for "catty"?
