How to solve level 336, 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 7: the mint patch is down to a single free square at row 4, column 7, so its cat settles there.
2. Every free square of the rose patch sits in column 1, so the rose cat must come from there and the rest of column 1 can be crossed out. Cat 2 of 7: the yellow patch is down to a single free square at row 1, column 2, so its cat settles there.
3. 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. Row 2 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 7: the only free square left in row 3 is column 1, so the cat goes there.
4. Row 7 only has free squares inside the aqua patch, so that patch's cat is spoken for and its squares outside the line can be crossed out. A cat at row 5, column 4 would leave row 6 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. 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. A cat at row 6, column 5 would leave row 7 with no home for its cat, so cross that square out. Cat 4 of 7: the lilac patch is down to a single free square at row 5, column 5, so its cat settles there.
5. Cat 5 of 7: the peach patch is down to a single free square at row 6, column 3, so its cat settles there.
6. Cat 6 of 7: the aqua patch is down to a single free square at row 7, column 6, so its cat settles there.
7. Cat 7 of 7: the sky patch is down to a single free square at row 2, column 4, so its cat settles there.
