Heya, I'm new :)

Hi an welcome to another UKer! Check out the UK section of the forum - I'm sure there is a thread there on where to find materials in the UK. Good luck!

Welcome to the forum!

Make sure to take note of the sticky threads on the top of each subforum they are full of info! I'm also going to give you a few links that might help you out you might have seen them but just to be safe I'll give them anyway. First is a link to a page on links then a link to Kleenmama's hayloft the hay there is absulutely great from what I've heard (I don't have piggies yet but I'm getting some soon). I also heard it is cheaper then Oxbrow (another online hay site). I hope you enjoy the site as much as I am and oh if you have any questions I'll be happy to answer them!

PS. Pigtures are a must!

Try looking at hardware stores...for example Canadian Tire, Home Hardware...etc. I believe that there is also a search tool on this website to see where people in your area found their supplies, it is very helpful.
I live in Canada, and we do not have a store called "Target" but it supposedly has cubes, I believe Walmart might too.

Good Luck finding your cubes!
