How to solve level 3744, 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. Every free square of the peach patch sits in column 10, so the peach cat must come from there and the rest of column 10 can be crossed out. A cat at row 3, column 9 would leave the rose 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 8 would leave the rose patch with no home for its cat, so cross that square out. A cat at row 5, column 9 would leave column 10 with no home for its cat, so cross that square out. A cat at row 6, column 6 would leave the lilac patch with no home for its cat, so cross that square out. A cat at row 6, column 9 would leave column 10 with no home for its cat, so cross that square out. A cat at row 8, column 1 would leave the lime patch with no home for its cat, so cross that square out. A cat at row 10, column 2 would leave the lime patch with no home for its cat, so cross that square out. The rose and coral patches all squeeze into columns 8 and 9, so those columns are reserved for them; every other square there can be crossed out. A cat at row 1, column 6 would leave row 2 with no home for its cat, so cross that square out. A cat at row 2, column 6 would leave row 1 with no home for its cat, so cross that square out. A cat at row 9, column 6 would leave the periwinkle patch with no home for its cat, so cross that square out. The yellow and lilac patches all squeeze into columns 6 and 7, so those columns are reserved for them; every other square there can be crossed out. Cat 1 of 10: the periwinkle patch is down to a single free square at row 10, column 5, so its cat settles there.
2. Every free square of the lime patch sits in row 9, so the lime cat must come from there and the rest of row 9 can be crossed out. A cat at row 7, column 2 would leave the aqua patch with no home for its cat, so cross that square out. A cat at row 8, column 2 would leave row 9 with no home for its cat, so cross that square out. A cat at row 5, column 3 would leave the aqua patch with no home for its cat, so cross that square out. The lilac, peach, aqua and coral patches all squeeze into rows 5, 6, 7 and 8, so those rows are reserved for them; every other square there can be crossed out. Column 4 only has free squares inside the sky patch, so that patch's cat is spoken for and its squares outside the line 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 8, column 3 would leave column 2 with no home for its cat, so cross that square out. Row 8 only has free squares inside the coral patch, so that patch's cat is spoken for and its squares outside the line can be crossed out. The rose and mint patches all squeeze into rows 3 and 4, so those rows are reserved for them; every other square there can be crossed out. Cat 2 of 10: column 6 has exactly one square left, at row 5, so the cat goes there.
3. Cat 3 of 10: the peach patch is down to a single free square at row 6, column 10, so its cat settles there.
4. Cat 4 of 10: the aqua patch is down to a single free square at row 7, column 3, so its cat settles there.
5. Cat 5 of 10: the mint patch is down to a single free square at row 4, column 1, so its cat settles there.
6. Cat 6 of 10: the rose patch is down to a single free square at row 3, column 8, so its cat settles there.
7. Cat 7 of 10: the yellow patch is down to a single free square at row 1, column 7, so its cat settles there.
8. Cat 8 of 10: the sky patch is down to a single free square at row 2, column 4, so its cat settles there.
9. Cat 9 of 10: the coral patch is down to a single free square at row 8, column 9, so its cat settles there.
10. Cat 10 of 10: the lime patch is down to a single free square at row 9, column 2, so its cat settles there.
