We changed from wood shavings for our guinea pigs cage to lining it with thick fleece - a kind of vet bed.
However, cleaning it is more tricky than I thought. The fleece is saturated with wee quite quickly and then it's covered in squished poo and hay and nuggets etc. We shake the loose stuff into a bin bag (well dd does) and then lump it onto the lawn to scrape off any extra. But it's quite messy and unpleasant and still soaked in wee. Then I stick it in the washing machine (we have two fleeces to alternate)
It's pretty unpleasant to do in the summer but can imagine it being worse in the colder, rainier months.
Are we missing something? I've bought puppy pads to go under the fleece as there were puddles at the bottom of their cage but haven't used them yet.
