I am new to this but so far I use torn up lidl simply range toilet paper, i tear up 10 squares and give this to her about twice a week or more often if she looks like she needs to be distracted as nest building seems to be her relaxing activity, her nest is a growing monster
for the cage floor (i have an Alaska cage), I bought a big Auboise (made from plant material horse bedding at 20kg for £10) and the first fill of the cage floor to about 5 inches used about 750g, i don't expect to have to do a full replacement for a while, just the top layer so am guessing this may last me the year??
