How to solve level 787, 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 yellow patch sits in row 1, so the yellow cat must come from there and the rest of row 1 can be crossed out. Every free square of the periwinkle patch sits in column 1, so the periwinkle cat must come from there and the rest of column 1 can be crossed out. 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 1, column 10 would leave the rose patch with no home for its cat, so cross that square out. Cat 1 of 10: the yellow patch is down to a single free square at row 1, column 9, so its cat settles there.
2. Cat 2 of 10: the rose patch is down to a single free square at row 3, column 10, so its cat settles there.
3. 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. Cat 3 of 10: the mint patch is down to a single free square at row 4, column 8, so its cat settles there.
4. Every free square of the peach patch sits in column 3, so the peach cat must come from there and the rest of column 3 can be crossed out. A cat at row 9, column 1 would leave column 2 with no home for its cat, so cross that square out. Cat 4 of 10: the periwinkle patch is down to a single free square at row 10, column 1, so its cat settles there.
5. Cat 5 of 10: the coral patch is down to a single free square at row 8, column 2, so its cat settles there.
6. 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 5, column 4 would leave column 3 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 4 would leave row 5 with no home for its cat, so cross that square out. A cat at row 6, column 5 would leave row 7 with no home for its cat, so cross that square out. A cat at row 6, column 6 would leave column 5 with no home for its cat, so cross that square out. A cat at row 7, column 4 would leave column 5 with no home for its cat, so cross that square out. Cat 6 of 10: column 4 has exactly one square left, at row 2, so the cat goes there.
7. A cat at row 6, column 7 would leave row 7 with no home for its cat, so cross that square out. Cat 7 of 10: the only free square left in row 6 is column 3, so the cat goes there.
8. Cat 8 of 10: the only free square left in row 5 is column 5, so the cat goes there.
9. Cat 9 of 10: the aqua patch is down to a single free square at row 7, column 6, so its cat settles there.
10. Cat 10 of 10: the lime patch is down to a single free square at row 9, column 7, so its cat settles there.
