The present invention relates to a collapsible animal faeces collector device (1) having a handle portion (2) and a receptacle support (6), supporting a receptacle (8) with an upwardly facing surface (10) for receiving a faecal deposit (24). The device (1) is of a lightweight construction, the handle (2) and receptacle support (6) have just sufficient strength to bear in cantilevered support an empty receptacle (8) for manipulation into a faeces-receiving position on the ground below an animal's anus, but insufficient strength to bear in cantilevered support a receptacle (8) loaded with faeces. The receptacle (8), when empty, is supported equally around the receptacle support (6) by a rim portion (12). When the device (1) loaded with faeces (24) is suspended, the rim portion (12) moves on the receptacle support (6) to collect together over the contents of the receptacle (8). The handle portion and receptacle support are preferably inflatable.
