We raised goats when we lived in CA. No they don't respect fences or any boundaries. If they can get thru, bingo! they will. We did not raise pygmys only the full sized critters.

Our neighbor, 5 houses down, raised pygmys. Real cute but a real pain in the a**. What people forget is they are animals and need to be taken care of properly and fed correctly.

I could preach on and sound like an idiot PETA member but I'd bet the animal shelters will be full of pygmy goats by the end of the year. Too bad for the animals that the humans in charge don't have a brain.
