Thanks for all the replies. I do use Chipsi super which is treated, hardened pine and spruce. I mix in my own home made paper bedding. I am planning to buy some carefresh next time I buy a bag of bedding as zooplus are having a sale. But couldn't that cause allergic reactions as it is wood pulp?
I really wanted to get fitch but I firstly found the website extremely confusing
and the couldn't see if they even posted to Ireland. And even then it was £11 to post to northern Ireland.
