How to solve level 1866, step by step

After every placed cat, cross out the rest of its row, its column, its patch and the four corner squares around it. The steps below assume you do (the in-game auto-paws assist does it for you).

1. Cat 1 of 10: the periwinkle patch is down to a single free square at row 10, column 1, so its cat settles there.
2. A cat at row 5, column 2 would leave the peach patch with no home for its cat, so cross that square out. A cat at row 7, column 3 would leave the peach patch with no home for its cat, so cross that square out. A cat at row 8, column 6 would leave the lime patch with no home for its cat, so cross that square out. A cat at row 8, column 9 would leave the coral patch with no home for its cat, so cross that square out. A cat at row 9, column 6 would leave the lime patch with no home for its cat, so cross that square out. A cat at row 9, column 7 would leave the coral patch with no home for its cat, so cross that square out. A cat at row 8, column 4 would leave the lime patch with no home for its cat, so cross that square out. A cat at row 8, column 5 would leave the lime patch with no home for its cat, so cross that square out. A cat at row 9, column 8 would leave the lime patch with no home for its cat, so cross that square out. A cat at row 7, column 9 would leave the coral patch with no home for its cat, so cross that square out. A cat at row 8, column 10 would leave the coral patch with no home for its cat, so cross that square out. The coral and lime patches all squeeze into rows 8 and 9, so those rows are reserved for them; every other square there can be crossed out. A cat at row 4, column 4 would leave the mint patch with no home for its cat, so cross that square out. A cat at row 7, column 7 would leave row 8 with no home for its cat, so cross that square out. A cat at row 7, column 8 would leave row 8 with no home for its cat, so cross that square out. The peach and aqua patches all squeeze into rows 6 and 7, so those rows are reserved for them; every other square there can be crossed out. A cat at row 3, column 6 would leave the lilac patch with no home for its cat, so cross that square out. A cat at row 4, column 7 would leave the lilac patch with no home for its cat, so cross that square out. A cat at row 5, column 5 would leave the lilac patch with no home for its cat, so cross that square out. A cat at row 4, column 3 would leave the mint patch with no home for its cat, so cross that square out. The mint and lilac patches all squeeze into rows 4 and 5, so those rows are reserved for them; every other square there can be crossed out. Cat 2 of 10: the rose patch is down to a single free square at row 3, column 7, so its cat settles there.
3. Cat 3 of 10: the lime patch is down to a single free square at row 9, column 5, so its cat settles there.
4. Cat 4 of 10: the lilac patch is down to a single free square at row 5, column 6, so its cat settles there.
5. Cat 5 of 10: the mint patch is down to a single free square at row 4, column 2, so its cat settles there.
6. Cat 6 of 10: the peach patch is down to a single free square at row 6, column 3, so its cat settles there.
7. Cat 7 of 10: the yellow patch is down to a single free square at row 1, column 4, so its cat settles there.
8. Cat 8 of 10: the aqua patch is down to a single free square at row 7, column 10, so its cat settles there.
9. Cat 9 of 10: the sky patch is down to a single free square at row 2, column 9, so its cat settles there.
10. Cat 10 of 10: the coral patch is down to a single free square at row 8, column 8, so its cat settles there.
