How to solve level 533, 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 rose patch sits in column 8, so the rose cat must come from there and the rest of column 8 can be crossed out. Every free square of the peach patch sits in column 5, so the peach cat must come from there and the rest of column 5 can be crossed out. Every free square of the coral patch sits in column 4, so the coral cat must come from there and the rest of column 4 can be crossed 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 2, column 2 would leave the sky patch with no home for its cat, so cross that square out. A cat at row 2, column 6 would leave column 7 with no home for its cat, so cross that square out. A cat at row 2, column 7 would leave column 8 with no home for its cat, so cross that square 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. Cat 1 of 8: the sky patch is down to a single free square at row 2, column 1, so its cat settles there.
2. Cat 2 of 8: the rose patch is down to a single free square at row 3, column 8, so its cat settles there.
3. Every free square of the lilac patch sits in row 5, so the lilac cat must come from there and the rest of row 5 can be crossed out. Row 4 only has free squares inside the mint patch, so that patch's cat is spoken for and its squares outside the line can be crossed out. Cat 3 of 8: column 7 has exactly one square left, at row 1, so the cat goes there.
4. Cat 4 of 8: column 6 has exactly one square left, at row 4, so the cat goes there.
5. 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 5 of 8: the only free square left in row 6 is column 5, so the cat goes there.
6. Cat 6 of 8: the coral patch is down to a single free square at row 8, column 4, so its cat settles there.
7. Cat 7 of 8: the aqua patch is down to a single free square at row 7, column 2, so its cat settles there.
8. Cat 8 of 8: the lilac patch is down to a single free square at row 5, column 3, so its cat settles there.
