I just bought the Kaytee Clean & Cozy from Amazon. It'll be a back up for me just in case fitch bedding 20kg would still be out of stock by next month.They were out of stock of the usual Kaytee clean and cosy that I use too, seems someones gone on a paper bedding shopping spree I had a look on Fitch's actual site as I wanted to try it this time and all they had were 10kg bales.
I have just spoken to Fitch (they are local for me) and they are struggling to get a supply of paper and this will get worse in July as their supplier is closed for the whole month. They have also had a huge increase in demand from guinea pig owners and have become a victim of their own success. They have the odd 20kg bags in their shop, so if you are local you can give them a call and if they have one in stock you can pay over the phone and then collect from the store (they can't deliver these).
Not sure how i will manage in July as i use about 1 x 20kg bag a month at the moment.
