Switching from woodshavings to Fitch

[sophiedoe]

Hello,

I have just received my huge 20kg of Fitch, it seems great. When is the best time to change my hammy over from woodshavings to the Fitch? We have had her for about 2.5 weeks and she has been in her current cage for just over a week. I don't want to unsettle her with too many changes in too short a time span.

Thanks!
