How to solve level 1975, 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 lime patch is down to a single free square at row 9, column 7, so its cat settles there.
2. A cat at row 1, column 2 would leave the sky patch with no home for its cat, so cross that square out. A cat at row 1, column 9 would leave the yellow patch with no home for its cat, so cross that square out. A cat at row 2, column 4 would leave the sky patch with no home for its cat, so cross that square out. A cat at row 2, column 10 would leave the rose patch with no home for its cat, so cross that square out. A cat at row 1, column 8 would leave the yellow patch with no home for its cat, so cross that square out. A cat at row 3, column 3 would leave the sky patch with no home for its cat, so cross that square out. A cat at row 3, column 10 would leave the yellow patch with no home for its cat, so cross that square out. A cat at row 4, column 8 would leave the rose patch with no home for its cat, so cross that square out. A cat at row 4, column 9 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 the rose patch with no home for its cat, so cross that square out. A cat at row 6, column 3 would leave the coral patch 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 7, column 2 would leave the coral patch with no home for its cat, so cross that square out. A cat at row 7, column 5 would leave column 6 with no home for its cat, so cross that square out. A cat at row 8, column 4 would leave the coral patch with no home for its cat, so cross that square out. The yellow and sky patches all squeeze into rows 1 and 2, so those rows are reserved for them; every other square there 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. A cat at row 5, column 8 would leave column 6 with no home for its cat, so cross that square out. A cat at row 5, column 10 would leave column 6 with no home for its cat, so cross that square out. Row 5 only has free squares inside the lilac patch, so that patch's cat is spoken for and its squares outside the line 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. A cat at row 5, column 5 would leave column 6 with no home for its cat, so cross that square out. Column 5 only has free squares inside the periwinkle 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 2 would leave column 1 with no home for its cat, so cross that square out. A cat at row 6, column 9 would leave column 8 with no home for its cat, so cross that square out. The yellow and rose patches all squeeze into columns 9 and 10, so those columns are reserved for them; every other square there can be crossed out. Cat 2 of 10: the aqua patch is down to a single free square at row 7, column 8, so its cat settles there.
3. Cat 3 of 10: the peach patch is down to a single free square at row 6, column 6, so its cat settles there.
4. Cat 4 of 10: the coral patch is down to a single free square at row 8, column 3, so its cat settles there.
5. Cat 5 of 10: the sky patch is down to a single free square at row 2, column 2, so its cat settles there.
6. Cat 6 of 10: the yellow patch is down to a single free square at row 1, column 10, so its cat settles there.
7. Cat 7 of 10: the rose patch is down to a single free square at row 3, column 9, so its cat settles there.
8. Cat 8 of 10: the mint patch is down to a single free square at row 4, column 1, so its cat settles there.
9. Cat 9 of 10: the lilac patch is down to a single free square at row 5, column 4, so its cat settles there.
10. Cat 10 of 10: the periwinkle patch is down to a single free square at row 10, column 5, so its cat settles there.
