Row 3: column 2, in the rose patch
Row 4: column 4, in the mint patch

Row 8: column 6, in the coral patch
How to solve level 204, 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 mint patch is down to a single free square at row 4, column 4, so its cat settles there.
Cat 2 of 8: the aqua patch is down to a single free square at row 7, column 1, so its cat settles there.
Row 8 only has free squares inside the coral patch, so that patch's cat is spoken for and its squares outside the line can be crossed out. A cat at row 1, column 2 would leave the rose 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 5 would leave the yellow patch with no home for its cat, so cross that square out. A cat at row 1, column 6 would leave the yellow patch with no home for its cat, so cross that square out. A cat at row 2, column 3 would leave the yellow patch with no home for its cat, so cross that square out. Cat 3 of 8: the rose patch is down to a single free square at row 3, column 2, so its cat settles there.
Row 5 only has free squares inside the lilac patch, so that patch's cat is spoken for and its squares outside the line can be crossed out. Row 6 only has free squares inside the peach 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 6 would leave row 6 with no home for its cat, so cross that square out. Cat 4 of 8: column 6 has exactly one square left, at row 8, so the cat goes there.
Cat 5 of 8: column 3 has exactly one square left, at row 1, so the cat goes there.
Cat 6 of 8: the sky patch is down to a single free square at row 2, column 8, so its cat settles there.
Cat 7 of 8: the lilac patch is down to a single free square at row 5, column 7, so its cat settles there.
Cat 8 of 8: the peach patch is down to a single free square at row 6, column 5, so its cat settles there.
