Kitten fights..

The Compyav Library is a place where you have to spot the differences between rooms earlier and later ten times. That is, if there are no differences (posters are in place, there's no cat, no water pistol, all the papers are in place, and the bushes with the fire extinguisher are too), you need to tell the main creature, Compyav. It's a computer with a talking gray cat on the screen. If there's a difference from the original library, you'll need to run across the dark corridor to the right. You'll then be teleported to another library room, where you can continue. If you guess wrong, you'll return to the original library and have to guess again where the differences are and where they aren't. After guessing all ten times, you'll return to the mansion.

The Whispering Garden is a labyrinth of stone walls and grass instead of a floor. It's filled with flowers and vines, as well as... statues of plump, winged cats. They've been petrified by a terrible force—light. Yes, right where the lamps shine, the cats first become ill, and then they're petrified. There are several souls that can be freed.

Rozzy is a pink cat with wings whose statue needs flowers to save her.
Mint is a green winged cat standing near the elevator leading to the next level. She can be saved by looking into her eyes.
Cloud is a blue winged kitten who sits in the most dangerous place. A simple paw push is enough for his soul to be released and leave this place.
Melissa is a gray winged cat chained to a stone wall in a dark room. Her head must be touched to release her soul.
Liana is a mint-colored winged cat whose statue is located in a fake elevator that has long since been broken. There, she is entangled in the vines. To free her soul, simply untangle the poor thing.

Backstage is a gloomy place, lit by an unpleasant yellow glow from the ceiling lamps. It's literally a labyrinth of walls and rooms. The walls are yellow, patterned. The floor is like a beige carpet.
The creatures that live there are Blacks, infected cats and dogs, and the Main Beast - a huge black cat with white, glowing, pupil-less eyes that emits a dark aura and leaves black footprints behind.
There is an exit to the next level - an elevator.

The shelter, or bunker, has a huge dining room, a corridor with doors to different rooms.
Manny's room is a forbidden area. Even Doc isn't allowed in there, or Manny will get angry. Access is only permitted with consent.
At the end of the corridor there is a huge door leading to the training room.

Wild Island has a mini restaurant with fish, coconuts, and rats. Basically, everything for cats. It's the smallest of all. That's where the bunker is.

The Learning Island is medium-sized. It features a small house where Simon used to work as a teacher and teach kittens. Next to the school is a swing set, and a little further away is the Wizard's Magic Tower.

The central island is the largest. It contains a white mansion with three floors: the first floor is large and spacious, containing a kitchen, a piano, and a table. The second floor is also large. There's a bridge leading to a room with a green bed and a hallway containing four more rooms: a bathroom, two bedrooms, and a restroom. The restroom contains a washing machine, which leads to Backstage. The third floor is the highest floor; it has no roof, as it is the roof itself. It has a wheel, similar to a hamster wheel, only made for cats.

The courtyard has a pool and two slides, starting from the second floor and going all the way to the pool. One, the longest, is rainbow-colored, and the second, shorter, is blue. There's also a green trampoline in the courtyard. There's a bridge leading to a whale that doubles as a bus.

This virus is extremely dangerous and affects every animal of every group, even insects and fish. Signs that you or someone else has this virus include: blackening of the fur, yellowing of the eyes, then whitening of the eyes, a desire for meat, and a fighting spirit and strength, even if the animal was previously weak.
Of course, the virus can be slowed with milk and blue potion, but this won't stop it completely. The infected specimen must be left in the backroom, or the eternal corridors, the garden of silence, and the pool room.

A black cat with white eyes is another victim of the ERROR virus.
Manya killed him, so he'll only appear in the story at your request. He's cold-blooded, unaware, and evil.

Katie is a white cat with black spots on her back and ears, who fixes robots and other things. She has a black heart-shaped spot on her side, which signifies her kindness. She likes to do all sorts of stupid things when she's bored. That's why she has fake orange butterfly wings on her back.

Otherwise, she's kind, selfless, and considerate.
