i found a cow milker through a friend, and she is willing to give it to me for free. she said it does not come with the tubes or anything, but has the actual steel base. can i use this for my goat, and what do i need to go with it? what are the thingys called that actually attach to the teat called? Is a cow milker too strong? i have a pygmy i would like to milk, would i have to get speciall teat thingys for her size?
