We have a treat tub. It's a clip lock one crammed with all sorts of goodies (dried chicken, and cheese paste ... Zanni's etc).

Rilly responds to her name, Itty also does, but Tinks? Well if I open one of the clips on the tread tub she can hear it from the other end of the house upstairs Maybe I should of called her *clip*

If I want them all in one room I just shout "Giiiirls" and then unclip the treat box works every time.

EDIT: Ooops forgot to answer original question. After neutering and vaccs and at least 12 months old would be the minimum I would choose before every even thinking about a harness. It only takes a scatty moment where determination wins over a secure harness, and they can be off. With all the best will in the world there will be times when you can't catch them. You might not of had it happen yet, but when you get a moment when you're trying to get hold of one of the little ones and they keep running away from you, imagine that situation outside
