Switching guinea pigs from pine to paper bedding

Switching away from pine shavings is a really good move — pine contains aromatic oils that can irritate guinea pigs' respiratory tracts over time, and with three piggies living together that air quality adds up fast. Paper-based bedding is softer, much more absorbent, and far kinder on their lungs. Before I point you to the best option, a couple of quick questions: are any of your three showing any signs of sneezing or eye discharge at the moment, and are you working with a C&C cage, a hutch, or something else? That'll help me get the sizing and quantity right for you.

Perfect — proactive is exactly the right approach, and a 2x4 C&C is a solid setup for a trio. For that footprint you're looking at filling roughly 140–160 litres of bedding space to get a good 8–10 cm depth, which is what guinea pigs need to burrow comfortably. My clear recommendation is Kaytee Clean & Cozy White paper bedding. It has outstanding liquid absorption — about five times its weight — it's virtually dust-free, and the white colour makes it easy to spot soiling and monitor your piggies' health at a glance. For three Himalayans in a 2x4 you'd want to start with the large 49.2-litre bag and see how your change frequency works out, but most people with a trio end up buying the jumbo size on a subscription to keep costs down. It compresses well in the bag so the volume goes further than it looks.

Yes, honestly just do a full clean-out and start fresh with the paper bedding in one go. There's no benefit to mixing the two — pine shavings underneath paper bedding would still off-gas, which defeats the whole purpose. Do a thorough cage wipe-down with a guinea pig-safe cleaner or plain white vinegar diluted in water, let it dry fully, then layer in your Kaytee Clean & Cozy to that 8–10 cm depth. Your trio may sniff around more than usual for a day or two — that's completely normal, they're just investigating the change. Within a week they'll be burrowing in it happily.

It does show soiling more visibly than grey or brown options — but that's actually the point. With three guinea pigs you want to be able to see at a glance where the wet patches are concentrating so you can do spot-cleans every day or two and keep the full change to once a week. If the visible soiling bothers you aesthetically, Kaytee also do a Natural (off-white/cream) version that's slightly more forgiving on appearance while keeping all the same performance benefits. Either way, the absorbency means it doesn't smell anywhere near as quickly as pine did, which most people notice within the first week.

Great choice — your Himalayans will thank you for it. One last tip: keep an eye on their breathing over the first couple of weeks after switching. If the pine was already causing mild irritation you may actually notice an improvement, which is a good sign. Enjoy the fluffier, less dusty cage, and feel free to come back if you want to look at hay racks or enrichment for the trio.
