Eikitchi (えいきっち Eikitchi, translates to Eternal Good Fortune) is Kazuma Kuwabara's female kitten. Kuwabara has a major weakness for kittens and he loves Eikitchi dearly. When Kuwabara found out that Eikitchi was kidnapped, he put it all on the line to save his beloved kitten.
Eikitchi's eye was threatened to be put out by enemy delinquents using a cigarrette in the manga, and a broken bottle in the anime, but in both situations Yusuke was able to save her.
Now fully grown into adulthood, she makes two final appearances in the final season: the first is in episode 97, when Kuwabara is seen sleeping in his bed instead of studying, and Eikitchi runs away in fear right before Shizuru Kuwabara stomps hard on her brother's head; the second in episode 98, in which Kuwabara hears meowing and calls out to his beloved cat, though it turns out to be Botan in his window. Kuwabara blushes and claims he was looking for his contact lenses (which he doesn't wear).
- She is briefly mentioned in the English anime, when Kuwabara sees the true form of Youko. He coments how guillible he was to let Kurama get near his cat.
- Eikitchi's cat breed is a Japanese Bobtail.
