Later this year I want to get guinea pigs for me (and ostensibly the DCs, but we all know they will be bored after a week).
I would like an indoor set up and have identified some potential indoor cages. I'm massively confused by bedding though. I've read pros and cons for everything. Articles where people rave about fleece, articles where they say it's mucky and cruel because piggies like to burrow in hay. I've seen recommendations for hay, megazorb, paper pellets, hemp based bedding, Uncle Tom cobbley and all.
So what is a good bet for a first time piggie owner?
