I guess the "farm" should be enough for your farming needs
catboard:
1. set your cat's status
出撃 - you take your cat with you
休憩 - rest
サブ出撃 - sub character-cat accompanies you
特訓 - special training - I have no idea what it does..
2. option: change your party. 1st screen are your regulars. Put your preferred cats here so you can switch between them faster (or train them)
3. Cat Gear
Submenu: 1: equip, 2. equip set 3. register set, 4. move set 5 delete set 6 move gear (in your box) 7. sell
4. change your cats appearance.
5. change the comments your cat can make.
6+7 not sure about that one. can't read the kanji and it's to small to trace, but it's probably something like delete, so stay away.
Why didn't I make a more helpful post about cat's back then x.x
I think special training levels up your cat even if you don't take it with you on quests, but lowers tension (if tension is 0 you can't let them train, have to rest)
as an addendum my post about the skills for your leader cat
So cat skills for your Main メイン cat:
*The level (5) cat skills only apply to the main cat.
*You gain these skills by putting (x) amount of cats with the trend in your team. (Regulars from the second option)

Combination Technique 合体技
*If you set out with two cats, they can do a combination technique, which is decided by the SubCat サブオトモ only (合体技 field)
ネコ式突撃隊
Cat assault Party - Cats will hop into a rocket ant fire themselves onto a monster. If they hit they do an attack similar to a hunters mounting attack
ネコ式火竜車
Cat's Firedrake Tank - Cat's will hop into a tank and shell monsters until ammunition is used up or the tank is destroyed (influenced by cats att and def stat)
ネコ式応援楽団
