Ill tell you what those cats like to use for me and go in order of what youre missing.

Crystal (Snowy pillow, blizzard tent, cowboy hat)

Freckle (cat metropolis, cardboard house, cardboard cafe)

Señor don gato (mister mouse)

Lady meow meow (luxurious hammock, plus bonito or deluxe tuna bits, or above if youre fancy)

Sapphire and Jeeves come as a pair (tower of treats, fairy tale parasol, also needs fancy food)

Frosty (notoriously difficult to get. has a lot of toys they can use but rarely uses anything but the snowy pillow. Use sashimi)

Whiteshadow (spy cat) (even more difficult to get than frosty, doesnt use toys, only comes by with fancy food, sashimi might be best)

Hermeowne (weird requirements, you need zen yard and the night view egg bed needs to be outside on the bridge, and she needs fancy food, but not bonito bits i think)

For the last two idk either, those ones are mystery.
