Upon doing so the animal traps himself and cannot get out until released. ## Claims ### Claim 1 An animal trap comprising: a housing forming an elongated chamber and having forward and rear walls; an opening in said forward wall for entry of an animal to be trapped; a platform member within said chamber and extending substantially the full length and width of said chamber, but being spaced from the walls of said cahmber sufficiently to permit pivoting therein about a horizontal axis from a first condition in which said platform slopes upwardly from said opening to a second condition in which said platform slopes downwardly with respect to said opening; means pivotally mounting said platform member within said chamber at a point spaced along said platform, whereby said platform can pivot about a horizontal axis; an indicator mounted on said platform and moveable thereby to indicate the condition of said platform with respect to said opening and to thus give an indication that an animal may be trapped in said trap; a locking device attached to said platform and operable to lock said platform in said second condition; and said indicator operably cooperating with said locking device and being movable by a user of said trap to unlock said locking device in said second condition. ### Claim 2 (depends on 1) The animal trap of claim 1, wherein: said indicator comprises an elongated member attached to said platform and moveable therewith. ### Claim 3 (depends on 2) The animal trap of claim 2, wherein: said indicator extends substantially vertically and is moveable in a substantially vertical plane. ### Claim 4 (depends on 1) The animal trap of claim 1, including: a projecting tube-like feed slot extending outwardly from the rear of said chamber above said platform. ### Claim 5 (depends on 4) The animal trap of claim 4, wherein: said feed slot is of a size to accept a preformed food pellet through its open rear end whereby said food pellet can be positioned within said tube-like slot inwardly of its open end sufficiently to be accessible to an animal in the interior of said chamber but being inaccessible from the exterior thereof. ### Claim 6 (depends on 5) The animal trap of claim 5, wherein: said tube-like slot comprises a projection of said chamber and is formed integrally therewith. ### Claim 7 (depends on 1) The animal trap of claim 1, wherein: said chamber is formed of a molded material, and has smooth inner surfaces; and said chamber is transparent. ### Claim 8 (depends on 1) The animal trap of claim 1, wherein: said locking device is attached to the forward end of said platform member; and said indicator is connected to said forward end of said platform member by means of said locking device. ### Claim 9 (depends on 8) The animal trap of claim 8, wherein: said indicator extends substantially vertically and is moveable in a substantially vertical plane from a lowered position thereof to a raised position thereof to give said indication of a trapped animal. ### Claim 10 (depends on 9) The animal trap of claim 9, wherein: said locking device is engageable with an opening provided in said housing so as to lock said platform in said second condition; and said indicator is horizontally movable in said raised position thereof so as to unlock said locking device by disengagement thereof from said opening in said housing. ### Claim 11 An animal trap comprising: a housing forming an elongated chamber and having forward and rear walls; an opening in said forward wall for entry of an animal to be trapped; a platform member within said chamber and extending substantially the full length and width of said chamber, but being spaced from the walls of said chamber sufficiently to permit pivoting therein about a horizontal axis from a first condition in which said platform slopes upwardly from said opening to a second condition in which said platform slopes downwardly with respect to said opening; means pivotally mounting said platform member within said chamber at a point spaced along said platform, whereby said platform can pivot about a horizontal axis; an indicator connected to said platform and moveable thereby to indicate the condition of said platform with respect to said opening and to thus give an indication that an animal may be trapped in said trap; said indicator comprising an elongated member attached to said platform and moveable therewith; means forming an opening in the upper wall of said chamber; and said indicator projecting through said opening and being moveable vertically therethrough upon movememnt of said platform. ### Claim 12 (depends on 11) The animal trap of claim 11, including: means pivotally securing said indicator member to said platform with said member projecting through said opening in the upper wall of said chamber and being of a length greater than the height of said chamber. ### Claim 13 An animal trap comprising: a housing forming an elongated chamber and having forward and rear walls; an opening in said forward wall for entry of an animal to be trapped; a platform member within said chamber and extending substantially the full length and width of said chamber, but being spaced from the walls of said chamber sufficiently to permit pivoting therein about a horizontal axis from a first condition in which said platform slopes upwardly from said opening to a second condition in which said platform slopes downwardly with respect to said opening; means pivotally mounting said platform member within said chamber at a point spaced along said platform, whereby said platform can pivot about a horizontal axis; an indicator connected to said platform and moveable thereby to indicate the condition of said platform with respect to said opening and to thus give an indication that an animal may be trapped in said trap; a locking device attached to said platform and operable to lock said platform in said second position; said locking device comprising a detent member connected to said platform and moveable therewith from a first position to a second position; an opening for said detent member positioned in alignment with said detent member, when said detent member is in said second position; and means for urging said detent member into said opening when in alignment therewith. ### Claim 14 (depends on 13) The animal trap of claim 13, wherein: the latter means is a spring. ### Claim 15 (depends on 13) The animal trap of claim 13, wherein: said detent member comprises a pin, and said indicator is supported on said pin. ### Claim 16 (depends on 15) The animal trap of claim 15, wherein: said pin is mounted in a support therefor on said platform and said means urging said pin is a resilient means in said support.
