A dip cup 10 comprising: a body 10 which receives a treatment agent from a supply line 16, the body 10 is in the form of a conical well for receiving a teat to be treated； at least one reservoir 13 that is connected by a fluid pathway (figure 4) to the well (12 figure 4) so that treatment agent passes between the well (12) and the at least one reservoir 13 when the dip cup is tipped, thereby avoiding spillage of a treatment agent. The fluid pathway may be in the form of a kettle drain 21. A system is also claimed, where the dip cup may be deployed with a system which automatically records number of uses； amount of treatment agent needed and automatically orders a new supply when levels of treatment agent are running low.
