How to solve level 179, 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).
Cat 1 of 8: the coral patch is down to a single free square at row 8, column 1, so its cat settles there.
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 2 of 8: the sky patch is down to a single free square at row 2, column 7, so its cat settles there.
Cat 3 of 8: the yellow patch is down to a single free square at row 1, column 5, so its cat settles there.
Every free square of the mint patch sits in column 8, so the mint cat must come from there and the rest of column 8 can be crossed out. Cat 4 of 8: the aqua patch is down to a single free square at row 7, column 6, so its cat settles there.
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. 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. Cat 5 of 8: the mint patch is down to a single free square at row 4, column 8, so its cat settles there.
A cat at row 5, column 3 would leave row 6 with no home for its cat, so cross that square out. Cat 6 of 8: the lilac patch is down to a single free square at row 5, column 4, so its cat settles there.
Cat 7 of 8: the peach patch is down to a single free square at row 6, column 2, so its cat settles there.
Cat 8 of 8: the rose patch is down to a single free square at row 3, column 3, so its cat settles there.
