How to solve level 730, 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 sky patch is down to a single free square at row 2, column 1, so its cat settles there.
2. Cat 2 of 10: the lilac patch is down to a single free square at row 5, column 2, so its cat settles there.
3. 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. 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 mint patch sits in row 4, so the mint cat must come from there and the rest of row 4 can be crossed out. Every free square of the coral patch sits in row 8, so the coral cat must come from there and the rest of row 8 can be crossed out. Every free square of the lime patch sits in column 3, so the lime cat must come from there and the rest of column 3 can be crossed out. Cat 3 of 10: the rose patch is down to a single free square at row 3, column 4, so its cat settles there.
4. Cat 4 of 10: the mint patch is down to a single free square at row 4, column 6, so its cat settles there.
5. Cat 5 of 10: the yellow patch is down to a single free square at row 1, column 5, so its cat settles there.
6. A cat at row 6, column 8 would leave the peach patch with no home for its cat, so cross that square out. A cat at row 7, column 7 would leave row 8 with no home for its cat, so cross that square out. A cat at row 6, column 9 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 row 8 with no home for its cat, so cross that square out. Cat 6 of 10: the peach patch is down to a single free square at row 6, column 7, so its cat settles there.
7. Cat 7 of 10: the coral patch is down to a single free square at row 8, column 8, so its cat settles there.
8. Cat 8 of 10: the aqua patch is down to a single free square at row 7, column 10, so its cat settles there.
9. Cat 9 of 10: the periwinkle patch is down to a single free square at row 10, column 9, so its cat settles there.
10. Cat 10 of 10: the lime patch is down to a single free square at row 9, column 3, so its cat settles there.
