Dogged determination

Well I took almost everything out of the room before I found the missing cat tablets

The laws of physics must have been broken since it is impossible for a container to fall off the relevant shelf and end up where it did - so clearly Tonks picked up the container and hid it!!

As an aside I took Kassie in Pets at home to get some stuff - she found their doggy tennis balls and went mad trying to get them off the shelf (yes I gave in)
