Are there any seeded cats on Level 200?

No. The first decoded frame is a blank 10x10 board with no seeded cat and no opening white X.

What is the red mistake on Level 200?

The red failed probe is r3c2 in the brown territory; the successful first brown cat goes at r4c2.

The tenth cat goes at r10c7 in the orange territory, completing Unbelievable with two hearts remaining; Level 200 keeps relatedLevels at [199].

Zoodoku level guide

expert 10 colors

Zoodoku Level 200 is an unseeded 10x10 cat board; follow r4c2, r1c1, r5c4, r3c5, r2c10, r9c9, r8c3, r7c6, r6c8, and r10c7 while avoiding red r3c2.

If the player asks you to sign in, open the video on YouTube instead.

Do not count red-probed r3c2; place the first cat at r4c2 in the brown territory and let the white X propagation settle.
Place the second cat at r1c1 in the green singleton.
Place the third cat at r5c4 in the pink singleton.
Place the fourth cat at r3c5 in the purple territory.
Place the fifth cat at r2c10 in the mauve right edge.
Place the sixth cat at r9c9 in the yellow singleton.
Place the seventh cat at r8c3 in the light-green territory.
Place the eighth cat at r7c6 in the teal territory.
Place the ninth cat at r6c8 in the light-blue territory.
Finish with the tenth cat at r10c7 in the orange territory, then confirm Unbelievable.

Colors in this level:

Green, Purple, Light-blue, Mauve, Brown, Orange, Light-green, Pink, Teal, Yellow

Do not tap r3c2: the source shows a red failed brown probe, while r4c2 is the successful first brown placement.
Do not replace the final pink/teal/light-blue/orange path with neighboring cells; the source closes at r7c6, r6c8, and r10c7 after r8c3.

Correct the opening brown probe by using r4c2, then take green r1c1 and pink r5c4 before the purple center.
Reserve the exact final sequence r7c6, r6c8, and r10c7 for the teal, light-blue, and orange closures; there is no Level 201 target.

Board notes 5 details

Layout: The 10x10 opening has a green upper-left singleton, purple and light-blue across the upper field, mauve on the upper-right, brown down the left, pink and teal through the center, light-green at the lower-left, yellow at r9c9, and orange across the lower-right.
Goal: Place ten cats in the verified source order r4c2, r1c1, r5c4, r3c5, r2c10, r9c9, r8c3, r7c6, r6c8, and r10c7, using each territory once.
Opening: The first decoded frame has no seeded cat and no opening X. The source first records red r3c2, then accepts brown r4c2; that placement starts the white X propagation before the green, pink, purple, and mauve moves.
Danger Zone: Red r3c2 is the failed brown probe and costs one heart; the successful first brown target is r4c2. The red X is not a propagated white exclusion.
Mechanics: This is an unseeded ten-cat 10x10 board and the endpoint of the requested range; the final capture shows Unbelievable, ten cats, and two hearts remaining.
