Glameow, the Catty Pokémon. When angry, it flashes its claws, but it also can purr quite affectionately.
– Ash’s Pokedex
Glameow is Gen IV’s cat Pokemon. It looks rather stuck-up, perhaps because it’s “glamorous”. Its tail is curly, like a spring. For some reason, its original sprite in DPPt was more blue, but got changed to more gray in HGSS.
In the anime, Zoey, Dawn’s contest friend and rival, has a Glameow, which she uses as her main contest Pokemon. It knows Shadowball for some reason. It uses its spring-like tail to bounce up and jump around. Dawn’s mom also has a Glameow, which she used to compete in contests when she was younger.
Stat-wise, it’s has more Speed than other stats.
