How to solve level 781, 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 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 periwinkle patch is down to a single free square at row 10, column 4, so its cat settles there.
3. Every free square of the sky patch sits in column 5, so the sky cat must come from there and the rest of column 5 can be crossed out. Cat 3 of 10: the lime patch is down to a single free square at row 9, column 7, so its cat settles there.
4. Every free square of the peach patch sits in column 10, so the peach cat must come from there and the rest of column 10 can be crossed out. A cat at row 2, column 6 would leave column 5 with no home for its cat, so cross that square out. Cat 4 of 10: the rose patch is down to a single free square at row 3, column 8, so its cat settles there.
5. Cat 5 of 10: the sky patch is down to a single free square at row 2, column 5, so its cat settles there.
6. Every free square of the mint patch sits in column 6, so the mint cat must come from there and the rest of column 6 can be crossed out. A cat at row 4, column 1 would leave row 5 with no home for its cat, so cross that square out. A cat at row 4, column 2 would leave row 5 with no home for its cat, so cross that square out. A cat at row 5, column 1 would leave column 2 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. Cat 6 of 10: the only free square left in row 4 is column 6, so the cat goes there.
7. A cat at row 6, column 1 would leave column 2 with no home for its cat, so cross that square out. A cat at row 6, column 2 would leave row 5 with no home for its cat, so cross that square out. A cat at row 6, column 3 would leave row 5 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 10, so the cat goes there.
8. A cat at row 7, column 2 would leave row 8 with no home for its cat, so cross that square out. A cat at row 7, column 3 would leave row 8 with no home for its cat, so cross that square out. Cat 8 of 10: the only free square left in row 7 is column 1, so the cat goes there.
9. Cat 9 of 10: the coral patch is down to a single free square at row 8, column 3, so its cat settles there.
10. Cat 10 of 10: the lilac patch is down to a single free square at row 5, column 2, so its cat settles there.
