Additionally, the litter sifter liner is designed to recycle the litter on a daily basis minimizing waste and maintaining upkeep. To achieve this, the liner has a sifter with a reinforced liner, and a plurality of identification tabs. The sifter is mounted into the base panel of the liner and positioned centrally with respect to the litter box sidewalls. This allows the transfer of litter to be contained within the perimeter of the litter box. The plurality of tabs are positioned offset with respect to each other. This indicates the total number of bags left for usage. ## Claims ### Claim 1 A litter sift liner comprising: a plurality of bags; at least one sifter; at least one reinforcing liner; the plurality of bags comprising a base bag, at least one sifting bag; the base bag and the sifting bag each comprising a base panel, a tubular sidewall, a foldable margin, and at least one indicator tab; the sifting bag being mounted within the base bag; the base panel being terminally connected to the tubular sidewall; the foldable margin being terminally connected to the tubular sidewall, opposite to the base panel; the indicator tab being adjacently connected to the foldable margin, opposite to the tubular sidewall; the sifter being integrated into the base panel of the sifting bag; and the reinforcing liner being superimposed onto the sifter. ### Claim 2 (depends on 1) The litter sifter liner as claimed in claim 1 comprising: the at least one sifting bag being a plurality of sifting bags; the plurality of sifting bags comprising an arbitrary bag and an adjacent bag; and the arbitrary bag being positioned in between the adjacent bag and the base bag. ### Claim 3 (depends on 1) The litter sifter liner as claimed in claim 1 comprising: the at least one indicator tab being a plurality of indicator tabs; and the plurality of indicator tabs being distributed around an opening of the base bag. ### Claim 4 (depends on 3) The litter sifter liner as claimed in claim 3 comprising: the plurality of indicator tabs being positioned offset from each other around the opening of the base bag. ### Claim 5 (depends on 1) The litter sifter liner as claimed in claim 1 comprising: wherein the foldable margin is in an upright configuration; and a lateral surface of the foldable margin being angularly offset from the tubular sidewall by an obtuse angle. ### Claim 6 (depends on 1) The litter sifter liner as claimed in claim 1 comprising: wherein the foldable margin is in a folded configuration; and a lateral surface of the foldable margin being angularly offset from the tubular sidewall by an acute angle. ### Claim 7 (depends on 1) The litter sifter liner as claimed in claim 1 comprising: a plurality of drawstrings; the plurality of drawstrings being integrated into the foldable margin for a corresponding bag, wherein the corresponding bag is from the plurality of bags; and the drawstring being positioned around an opening of the corresponding bag. ### Claim 8 (depends on 1) The litter sifter liner as claimed in claim 1 comprising: a plurality of fill-level indicators; the plurality of fill-level indicators being adjacently connected to the tubular sidewall; and the plurality of fill-level indicators being linearly distributed along the tubular sidewall. ### Claim 9 A litter sift liner comprising: a plurality of bags; at least one sifter; at least one reinforcing liner; the plurality of bags comprising a base bag, at least one sifting bag; the base bag and the sifting bag each comprising a base panel, a tubular sidewall, a foldable margin, and at least one indicator tab; the sifting bag being mounted within the base bag; the base panel being terminally connected to the tubular sidewall; the foldable margin being terminally connected to the tubular sidewall, opposite to the base panel; the indicator tab being adjacently connected to the foldable margin, opposite to the tubular sidewall; the sifter being integrated into the base panel of the sifting bag; the reinforcing liner being superimposed onto the sifter; the at least one indicator tab being a plurality of indicator tabs; and the plurality of indicator tabs being distributed around an opening of the base bag. ### Claim 10 (depends on 9) The litter sifter liner as claimed in claim 9 comprising: the at least one sifting bag being a plurality of sifting bags; the plurality of sifting bags comprising an arbitrary bag and an adjacent bag; and the arbitrary bag being positioned in between the adjacent bag and the base bag. ### Claim 11 (depends on 9) The litter sifter liner as claimed in claim 9 comprising: the plurality of indicator tabs being positioned offset from each other around the opening of the base bag. ### Claim 12 (depends on 9) The litter sifter liner as claimed in claim 9 comprising: wherein the foldable margin is in an upright configuration; and a lateral surface of the foldable margin being angularly offset from the tubular sidewall by an obtuse angle. ### Claim 13 (depends on 9) The litter sifter liner as claimed in claim 9 comprising: wherein the foldable margin is in a folded configuration; and a lateral surface of the foldable margin being angularly offset from the tubular sidewall by an acute angle. ### Claim 14 (depends on 9) The litter sifter liner as claimed in claim 9 comprising: a plurality of drawstrings; the plurality of drawstrings being integrated into the foldable margin for a corresponding bag, wherein the corresponding bag is from the plurality of bags; and the drawstring being positioned around an opening of the corresponding bag. ### Claim 15 (depends on 9) The litter sifter liner as claimed in claim 9 comprising: a plurality of fill-level indicators; the plurality of fill-level indicators being adjacently connected to the tubular sidewall; and the plurality of fill-level indicators being linearly distributed along the tubular sidewall.
