How to solve level 741, 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 3, so its cat settles there.
2. Cat 2 of 10: the periwinkle patch is down to a single free square at row 10, column 1, so its cat settles there.
3. Every free square of the mint patch sits in column 10, so the mint cat must come from there and the rest of column 10 can be crossed out. Every free square of the lilac patch sits in column 5, so the lilac cat must come from there and the rest of column 5 can be crossed out. Row 8 only has free squares inside the coral patch, so that patch's cat is spoken for and its squares outside the line can be crossed out. A cat at row 3, column 9 would leave the rose patch with no home for its cat, so cross that square out. A cat at row 4, column 7 would leave the rose patch with no home for its cat, so cross that square out. A cat at row 5, column 8 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 column 10 with no home for its cat, so cross that square out. Every free square of the peach patch sits in row 6, so the peach cat must come from there and the rest of row 6 can be crossed out. Every free square of the aqua patch sits in column 2, so the aqua cat must come from there and the rest of column 2 can be crossed out. Column 4 only has free squares inside the sky patch, so that patch's cat is spoken for and its squares outside the line can be crossed out. Cat 3 of 10: column 6 has exactly one square left, at row 8, so the cat goes there.
4. Cat 4 of 10: the lilac patch is down to a single free square at row 5, column 5, so its cat settles there.
5. Cat 5 of 10: the mint patch is down to a single free square at row 4, column 10, so its cat settles there.
6. Cat 6 of 10: the rose patch is down to a single free square at row 3, column 8, so its cat settles there.
7. Cat 7 of 10: the peach patch is down to a single free square at row 6, column 9, so its cat settles there.
8. Cat 8 of 10: the yellow patch is down to a single free square at row 1, column 7, so its cat settles there.
9. Cat 9 of 10: the sky patch is down to a single free square at row 2, column 4, so its cat settles there.
10. Cat 10 of 10: the aqua patch is down to a single free square at row 7, column 2, so its cat settles there.
