I have used Fitch for years. No smells and nice - hamsters like it too. It’s just recycled food grade paper. It comes in 10kg or 20kg bags so it’s economical too. I get the 10kg bag for £22 including delivery. Lasts about 6 months with a 100 Cm cage. It’s only available online - they deliver within a couple of days usually. Kaytee clean and cosy is similar but compressed. However my last bag was dusty so I don’t know if they have changed it recently. So I stick with Fitch (no dust).
