How to solve level 133, 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).
A cat at row 1, column 3 would leave the sky patch with no home for its cat, so cross that square out. A cat at row 2, column 1 would leave the sky patch with no home for its cat, so cross that square out. A cat at row 2, column 2 would leave the rose patch with no home for its cat, so cross that square out. A cat at row 1, column 4 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 the mint patch with no home for its cat, so cross that square out. A cat at row 3, column 2 would leave the sky patch with no home for its cat, so cross that square out. 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 1 of 7: the aqua patch is down to a single free square at row 7, column 2, so its cat settles there.
Cat 2 of 7: the sky patch is down to a single free square at row 2, column 3, 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 3 of 7: the rose patch is down to a single free square at row 3, column 1, so its cat settles there.
Cat 4 of 7: the mint patch is down to a single free square at row 4, column 6, so its cat settles there.
Cat 5 of 7: the yellow patch is down to a single free square at row 1, column 5, so its cat settles there.
Cat 6 of 7: the peach patch is down to a single free square at row 6, column 7, so its cat settles there.
Cat 7 of 7: the lilac patch is down to a single free square at row 5, column 4, so its cat settles there.
