7. Row 7: column 4, in the aqua patch

How to solve level 111, 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 aqua patch is down to a single free square at row 7, column 4, so its cat settles there.
2. Cat 2 of 7: the sky patch is down to a single free square at row 2, column 5, so its cat settles there.
3. Cat 3 of 7: the yellow patch is down to a single free square at row 1, column 7, so its cat settles there.
4. 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. Every free square of the peach patch sits in column 1, so the peach cat must come from there and the rest of column 1 can be crossed out. Row 3 only has free squares inside the rose patch, so that patch's cat is spoken for and its squares outside the line can be crossed out. A cat at row 4, column 3 would leave row 3 with no home for its cat, so cross that square out. Cat 4 of 7: the only free square left in row 4 is column 6, so the cat goes there.
5. A cat at row 5, column 1 would leave row 6 with no home for its cat, so cross that square out. Cat 5 of 7: the peach patch is down to a single free square at row 6, column 1, so its cat settles there.
6. Cat 6 of 7: the lilac patch is down to a single free square at row 5, column 3, so its cat settles there.
7. Cat 7 of 7: the rose patch is down to a single free square at row 3, column 2, so its cat settles there.
