Delcatty in depth
A grass that cats chase
The Japanese name, エネコロロ (Enekororo), is built from three parts: enokorogusa, the green foxtail grass that grows in any roadside ditch; neko, cat; and kokoro, heart. Skitty is エネコ (Eneko), just the first two and nothing more. The grass isn’t decorative: the foxtail’s spike is exactly what gets waved in front of a cat to make it chase, and Skitty’s tail ends in a tuft that the Pokémon pursues tirelessly. Delcatty’s is no longer something to chase, but something to show off.
The English name is flatter: delicate and catty, the result rather than the process. The design starts with a domestic cat, with details borrowed from the lynx — the fur framing its face and the tufts on its ears —, while the purple collar has been read both as a pincushion and as one of those travel neck pillows, an interpretation that fits an animal that sleeps wherever it happens to be.
The Ability arrived one generation late
In Ruby and Sapphire, it only had Cute Charm. Normalize didn’t exist yet: it was added in Generation IV, and has remained exclusive to this line ever since, with no other Pokémon having it. Generation VII gave it two things at once: the small power boost for converted moves and a Speed increase, the only stat adjustment it has received in its entire history. Until Sun and Moon, it was considerably slower than it is now, leaving its stat sheet without a single category above average.
Wonder Skin came later as a Hidden Ability, and it’s the most useful of the three for surviving one more turn: it blocks a good number of the status moves thrown at it precisely because it can’t take direct hits.
When to spend the stone
The Moon Stone is a scarce resource in almost every game where it appears, and Delcatty competes for it with Wigglytuff and the Clefairy line. The difference here is that evolution doesn’t open any new doors: Delcatty’s level-up move list is entirely available at level 1, and the good stuff is in there — Heal Bell, Copycat, Play Rough, Baby-Doll Eyes, Disarming Voice — alongside oddities such as Tail Whip and Fury Swipes, which with 18 power per hit don’t justify taking up a moveslot.
The sensible thing is to leave Skitty levelling up until it has everything you want to teach it, then use the stone, because what it gains from the change is stat points, not a new movepool.
The other cat on the list
The obvious comparison is Persian, a pure Normal type, feline and with the same theoretical role as a fast attacker. Persian evolves by level, without spending an item, and ends up faster and stronger. Delcatty is left with the support role: Heal Bell and Copycat aren’t found on most Normal types, and Attract aimed at a mostly male opposing team makes sense when three out of every four Delcatty are female.
It debuted in the anime in the episode A Date With Delcatty, in the hands of a character called Georgio. It’s a Pokémon that has always been sold on its fur and its poise, and its Pokédex entries are among the few that describe a creature that simply refuses to fight: if something bothers it while it’s asleep, it changes location and carries on sleeping.
