How to solve level 1797, 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. A cat at row 2, column 4 would leave column 3 with no home for its cat, so cross that square out. A cat at row 6, column 2 would leave the lilac patch with no home for its cat, so cross that square out. A cat at row 7, column 8 would leave the lime patch with no home for its cat, so cross that square out. A cat at row 8, column 1 would leave the lilac patch with no home for its cat, so cross that square out. A cat at row 8, column 7 would leave the lime patch with no home for its cat, so cross that square out. A cat at row 9, column 2 would leave the periwinkle patch with no home for its cat, so cross that square out. A cat at row 9, column 9 would leave the lime patch with no home for its cat, so cross that square out. The lilac and periwinkle patches all squeeze into columns 1 and 2, so those columns are reserved for them; every other square there can be crossed out. Every free square of the sky patch sits in column 3, so the sky cat must come from there and the rest of column 3 can be crossed out. A cat at row 2, column 9 would leave row 1 with no home for its cat, so cross that square out. A cat at row 3, column 4 would leave column 3 with no home for its cat, so cross that square out. The rose, coral and lime patches all squeeze into columns 8, 9 and 10, so those columns are reserved for them; every other square there can be crossed out. Every free square of the aqua patch sits in column 7, so the aqua cat must come from there and the rest of column 7 can be crossed out. A cat at row 8, column 6 would leave column 7 with no home for its cat, so cross that square out. A cat at row 8, column 8 would leave column 7 with no home for its cat, so cross that square out. A cat at row 9, column 10 would leave the lime patch with no home for its cat, so cross that square out. A cat at row 10, column 9 would leave the lime patch with no home for its cat, so cross that square out. Every free square of the coral patch sits in column 10, so the coral cat must come from there and the rest of column 10 can be crossed out. A cat at row 1, column 4 would leave row 2 with no home for its cat, so cross that square out. Column 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. The aqua, coral, lime and periwinkle patches all squeeze into rows 7, 8, 9 and 10, so those rows are reserved for them; every other square there can be crossed out. Cat 1 of 10: column 2 has exactly one square left, at row 10, so the cat goes there.
  2. 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 2 of 10: the lilac patch is down to a single free square at row 5, column 1, so its cat settles there.
  3. Cat 3 of 10: the mint patch is down to a single free square at row 4, column 4, so its cat settles there.
  4. Cat 4 of 10: the sky patch is down to a single free square at row 2, column 3, so its cat settles there.
  5. Cat 5 of 10: the only free square left in row 3 is column 9, so the cat goes there.
  6. Cat 6 of 10: the lime patch is down to a single free square at row 9, column 8, so its cat settles there.
  7. Cat 7 of 10: the aqua patch is down to a single free square at row 7, column 7, so its cat settles there.
  8. Cat 8 of 10: the peach patch is down to a single free square at row 6, column 5, so its cat settles there.
  9. Cat 9 of 10: the yellow patch is down to a single free square at row 1, column 6, so its cat settles there.
  10. Cat 10 of 10: the coral patch is down to a single free square at row 8, column 10, so its cat settles there.
