Could we keep an Alpaca?

On the weekend my lovely Daughters, Husband and I popped into The Harvest Festival in Wollongong! They had a little "Mini Farm" there. There were rabbits, chooks, a calf, goats and the sweetest and softest Alpaca. Ofcourse the girls fell quite in "love" and thought maybe we could get one....if only we had the space! Now they've got to try and convince their Nan and Pop who live in the Country that they should get one or two..... Who could resist their sweet faces??
