MAJOR SPOILERS FOR UMINEKO AHEAD

(has some added interest for those of you who believe kris will lose their hand)

and a few quotes from episode 8 of the vn

"That single cat should make you as scared as being surrounded by a crowd of vicious beasts. Plus, they're cats. They've got good senses, and they'll call for their friends. If they spot you, you'd better be prepared for what happens next."

"If Battler's group was found, the cats would report it instantly. They would probably form a pack, open their large mouths and swallow them in a single gulp."

"The number she dialed was short. It was probably an internal line. However, after listening to it ring several times, she slammed the receiver down again, finally managing to break the phone. '......Gather all the cats who aren't busy. ... The cats I had guarding the key aren't responding!!!'"
