How to solve level 1964, 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 yellow patch is down to a single free square at row 1, column 10, so its cat settles there.
2. A cat at row 3, column 2 would leave the sky patch with no home for its cat, so cross that square out. A cat at row 3, column 8 would leave the mint patch with no home for its cat, so cross that square out. A cat at row 4, column 7 would leave the mint patch with no home for its cat, so cross that square out. A cat at row 5, column 8 would leave the peach patch with no home for its cat, so cross that square out. Every free square of the mint patch sits in row 4, so the mint cat must come from there and the rest of row 4 can be crossed out. A cat at row 3, column 9 would leave row 4 with no home for its cat, so cross that square out. A cat at row 5, column 9 would leave row 4 with no home for its cat, so cross that square out. Every free square of the peach patch sits in row 6, so the peach cat must come from there and the rest of row 6 can be crossed out. A cat at row 7, column 8 would leave row 6 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 row 9 with no home for its cat, so cross that square out. The sky, rose and lilac patches all squeeze into rows 2, 3 and 5, so those rows are reserved for them; every other square there can be crossed out. A cat at row 2, column 6 would leave row 5 with no home for its cat, so cross that square out. A cat at row 6, column 7 would leave row 5 with no home for its cat, so cross that square out. A cat at row 7, column 4 would leave the coral patch with no home for its cat, so cross that square out. A cat at row 7, column 9 would leave row 6 with no home for its cat, so cross that square out. A cat at row 8, column 2 would leave the coral patch with no home for its cat, so cross that square out. A cat at row 8, column 6 would leave the aqua patch with no home for its cat, so cross that square out. The aqua and coral patches all squeeze into rows 7 and 8, so those rows are reserved for them; every other square there can be crossed out. The sky and lime patches all squeeze into columns 1 and 2, so those columns are reserved for them; every other square there can be crossed out. Every free square of the coral patch sits in column 3, so the coral cat must come from there and the rest of column 3 can be crossed out. A cat at row 8, column 4 would leave row 7 with no home for its cat, so cross that square out. The mint and peach patches all squeeze into columns 8 and 9, so those columns are reserved for them; every other square there can be crossed out. Cat 2 of 10: the only free square left in row 8 is column 3, so the cat goes there.
3. Cat 3 of 10: column 2 has exactly one square left, at row 2, so the cat goes there.
4. Every free square of the rose patch sits in column 7, so the rose cat must come from there and the rest of column 7 can be crossed out. A cat at row 4, column 8 would leave column 7 with no home for its cat, so cross that square out. Cat 4 of 10: the mint patch is down to a single free square at row 4, column 9, so its cat settles there.
5. Cat 5 of 10: the peach patch is down to a single free square at row 6, column 8, so its cat settles there.
6. Cat 6 of 10: the rose patch is down to a single free square at row 3, column 7, so its cat settles there.
7. Cat 7 of 10: the lilac patch is down to a single free square at row 5, column 6, so its cat settles there.
8. Cat 8 of 10: the aqua patch is down to a single free square at row 7, column 5, so its cat settles there.
9. Cat 9 of 10: the periwinkle patch is down to a single free square at row 10, column 4, so its cat settles there.
10. Cat 10 of 10: the lime patch is down to a single free square at row 9, column 1, so its cat settles there.
