How to solve level 1569, 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. A cat at row 1, column 8 would leave the sky patch with no home for its cat, so cross that square out. Every free square of the yellow patch sits in column 9, so the yellow cat must come from there and the rest of column 9 can be crossed out. A cat at row 2, column 8 would leave column 9 with no home for its cat, so cross that square out. A cat at row 2, column 9 would leave the sky patch with no home for its cat, so cross that square out. Cat 1 of 9: the yellow patch is down to a single free square at row 1, column 9, so its cat settles there.
2. A cat at row 3, column 2 would leave the rose patch with no home for its cat, so cross that square out. A cat at row 3, column 6 would leave the sky patch with no home for its cat, so cross that square out. A cat at row 3, column 7 would leave the sky patch with no home for its cat, so cross that square out. A cat at row 4, column 7 would leave the sky 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. A cat at row 7, column 8 would leave the peach patch with no home for its cat, so cross that square out. The sky and rose patches all squeeze into rows 2 and 3, so those rows are reserved for them; every other square there can be crossed out. A cat at row 4, column 6 would leave the lilac patch with no home for its cat, so cross that square 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 6, column 5 would leave column 6 with no home for its cat, so cross that square out. The peach, aqua, coral and lime patches all squeeze into rows 6, 7, 8 and 9, so those rows are reserved for them; every other square there can be crossed out. A cat at row 7, column 7 would leave row 6 with no home for its cat, so cross that square out. A cat at row 8, column 5 would leave row 7 with no home for its cat, so cross that square out. The sky and peach patches all squeeze into columns 7 and 8, so those columns are reserved for them; every other square there can be crossed out. Cat 2 of 9: the lilac patch is down to a single free square at row 5, column 6, so its cat settles there.
3. Cat 3 of 9: column 7 has exactly one square left, at row 2, so the cat goes there.
4. Cat 4 of 9: the rose patch is down to a single free square at row 3, column 1, so its cat settles there.
5. Every free square of the coral patch sits in column 2, so the coral cat must come from there and the rest of column 2 can be crossed 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 6, column 4 would leave row 7 with no home for its cat, so cross that square out. Cat 5 of 9: the aqua patch is down to a single free square at row 7, column 5, so its cat settles there.
6. Cat 6 of 9: the only free square left in row 6 is column 8, so the cat goes there.
7. A cat at row 8, column 3 would leave row 9 with no home for its cat, so cross that square out. Cat 7 of 9: the only free square left in row 8 is column 2, so the cat goes there.
8. Cat 8 of 9: the lime patch is down to a single free square at row 9, column 4, so its cat settles there.
9. Cat 9 of 9: the mint patch is down to a single free square at row 4, column 3, so its cat settles there.
