How to solve level 1947, 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 rose patch sits in row 3, so the rose cat must come from there and the rest of row 3 can be crossed out. A cat at row 2, column 1 would leave row 3 with no home for its cat, so cross that square out. A cat at row 1, column 3 would leave the yellow patch with no home for its cat, so cross that square out. A cat at row 2, column 2 would leave row 3 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. A cat at row 4, column 1 would leave row 3 with no home for its cat, so cross that square out. A cat at row 4, column 2 would leave row 3 with no home for its cat, so cross that square out. A cat at row 4, column 8 would leave the lilac patch with no home for its cat, so cross that square out. A cat at row 5, column 10 would leave the lilac 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 9, column 5 would leave column 4 with no home for its cat, so cross that square out. A cat at row 9, column 10 would leave the coral patch with no home for its cat, so cross that square out. Every free square of the periwinkle patch sits in row 10, so the periwinkle cat must come from there and the rest of row 10 can be crossed out. A cat at row 7, column 3 would leave column 4 with no home for its cat, so cross that square out. A cat at row 7, column 5 would leave column 4 with no home for its cat, so cross that square out. A cat at row 8, column 5 would leave column 4 with no home for its cat, so cross that square out. A cat at row 5, column 6 would leave column 5 with no home for its cat, so cross that square out. A cat at row 6, column 7 would leave column 5 with no home for its cat, so cross that square out. The yellow and rose patches all squeeze into columns 1 and 2, so those columns are reserved for them; every other square there can be crossed out. Cat 1 of 10: the mint patch is down to a single free square at row 4, column 3, so its cat settles there.
2. Cat 2 of 10: the rose patch is down to a single free square at row 3, column 1, so its cat settles there.
3. Cat 3 of 10: the yellow patch is down to a single free square at row 1, column 2, so its cat settles there.
4. Cat 4 of 10: the lilac patch is down to a single free square at row 5, column 9, so its cat settles there.
5. Every free square of the sky patch sits in row 2, so the sky cat must come from there and the rest of row 2 can be crossed out. Every free square of the coral patch sits in column 10, so the coral cat must come from there and the rest of column 10 can be crossed out. A cat at row 8, column 7 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 row 10 with no home for its cat, so cross that square out. A cat at row 9, column 8 would leave row 10 with no home for its cat, so cross that square out. A cat at row 8, column 4 would leave row 9 with no home for its cat, so cross that square out. Every free square of the lime patch sits in column 6, so the lime cat must come from there and the rest of column 6 can be crossed out. Row 6 only has free squares inside the peach patch, so that patch's cat is spoken for and its squares outside the line can be crossed out. Cat 5 of 10: the only free square left in row 9 is column 6, so the cat goes there.
6. Cat 6 of 10: the periwinkle patch is down to a single free square at row 10, column 8, so its cat settles there.
7. Cat 7 of 10: the aqua patch is down to a single free square at row 7, 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 5, so its cat settles there.
9. Cat 9 of 10: the peach patch is down to a single free square at row 6, column 4, so its cat settles there.
10. Cat 10 of 10: the coral patch is down to a single free square at row 8, column 10, so its cat settles there.
