Hi jarbax, hope your piggies like the Orchard Grass, I ordered some too. Just a quick note on your order from Thistle Cavies: it's a family-run rescue, and I just found out today when I inquired as to why my order hadn't shown up that a member of the family has been ill in hospital so they are a bit behind with orders. They are usually very fast, but mine has been delayed a bit because the lady that runs it has been very short of time. I told her it was no problem, I was just worried the royal mail sorting office had eaten it! Anyway, she's sent it, and you'll probably get yours quickly too, since she is sorting out the orders now. There probably won't be a delay, but just in case you started to worry!
If you want larger quantities of Orchard Grass, they can get it in for you. Or SPH supplies also sell it along with Western Timothy. There are lots of different sizes, all the way up to 50lb! Anyway, the address is
www.sphsupplies.co.uk, and they will make a donation to Reading Guinea Pig Rescue if you mention them in the comments box on the order form. I bought hay from them, their service is excellent, and the hay is a quick turnover. Mine was, and is, lovely and green and fresh. It's cheaper to buy in bulk, but make sure you can store it, and will use it up before it goes stale if you get a larger bag/box.
Hope your piggie(s) like their new hay.
