How to solve level 1784, 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 10, so its cat settles there.
2. Every free square of the sky patch sits in column 1, so the sky cat must come from there and the rest of column 1 can be crossed out. A cat at row 2, column 3 would leave the yellow patch with no home for its cat, so cross that square out. A cat at row 2, column 8 would leave the rose patch with no home for its cat, so cross that square out. A cat at row 3, column 2 would leave column 1 with no home for its cat, so cross that square out. A cat at row 3, column 5 would leave the mint patch with no home for its cat, so cross that square out. A cat at row 5, column 4 would leave the mint patch with no home for its cat, so cross that square out. A cat at row 6, column 3 would leave row 7 with no home for its cat, so cross that square out. A cat at row 7, column 8 would leave the coral patch with no home for its cat, so cross that square out. A cat at row 8, column 3 would leave the lime patch with no home for its cat, so cross that square out. A cat at row 8, column 7 would leave the coral patch with no home for its cat, so cross that square out. A cat at row 8, column 8 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. The yellow, sky, rose and mint patches all squeeze into rows 1, 2, 3 and 4, so those rows are reserved for them; every other square there can be crossed out. A cat at row 5, column 3 would leave column 6 with no home for its cat, so cross that square out. A cat at row 5, column 5 would leave column 6 with no home for its cat, so cross that square out. A cat at row 6, column 5 would leave column 6 with no home for its cat, so cross that square out. A cat at row 6, column 7 would leave column 6 with no home for its cat, so cross that square out. The yellow, peach and lime patches all squeeze into columns 2, 3 and 4, so those columns are reserved for them; every other square there can be crossed out. Cat 2 of 10: the mint patch is down to a single free square at row 4, column 5, so its cat settles there.
3. Column 6 only has free squares inside the aqua patch, so that patch's cat is spoken for and its squares outside the line can be crossed out. A cat at row 2, column 2 would leave column 1 with no home for its cat, so cross that square out. Every free square of the yellow patch sits in row 1, so the yellow cat must come from there and the rest of row 1 can be crossed out. Cat 3 of 10: column 7 has exactly one square left, at row 5, so the cat goes there.
4. Cat 4 of 10: the aqua patch is down to a single free square at row 7, column 6, so its cat settles there.
5. Cat 5 of 10: the peach patch is down to a single free square at row 6, column 2, so its cat settles there.
6. Cat 6 of 10: the lime patch is down to a single free square at row 9, 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 coral patch is down to a single free square at row 8, column 9, so its cat settles there.
9. Cat 9 of 10: the rose patch is down to a single free square at row 3, column 8, so its cat settles there.
10. Cat 10 of 10: the sky patch is down to a single free square at row 2, column 1, so its cat settles there.
