I tried some but personally didn't like it. The pile is quite deep and the piggies seemed to struggle to walk on it with their short legs more than on the flat fleece. George in particular has arthritis and nails that grow curly in all directions so he snagged a bit - he didn't get completely stuck but he didn't choose to go on it. And it made a mess of the washing machine. The homemade (flat) fleece/zorb/fleece bedding we have is absorbent and quite cushioned and much easier to shake out, brush (rubber brush) and wash. We also have these snuggle tunnels...
These are comfy and plush but not absorbent - if piggy pees in one it stays wet (but you can just flip the triangle round). They also collapse after a dozen washes or so, but mine still push their way in. The pigs have learnt to pee outside before they go in - the poops just shake out. George can keep a tunnel dry all week but if Flora gets in his she'll deliberately pee all over his nice boar stink straight away just to annoy him!
The final thing is this which was sold as a puppy mat for about £4. I cut it in half and just sewed up the rough edges. It's got cheap sponge in the middle and a cheap nylon back and the fluff is that long, smooth fleece that doesn't catch nails but stays wet when peed on so actually it should have been a soggy disaster but Flora realised straight away about the puddle problem and has never peed on it again. We use it in 'Flora's penthouse': she's the only one who likes to sleep up top.
So I suppose it depends on how your piggies are with absorbent surfaces and what exactly is the problem with the paw you are trying to deal with. For many years we just used bedding and we still do in the base of the cages... we tried a plastic 'toilet corner' that nobody ever went in and of course piggies cannot be toilet trained but for some reason it surprised me that they could choose
not to pee somewhere - especially somewhere warm and fluffy! They poop everywhere - don't get me wrong - but as poops just shake off. If they're going in somewhere for a nap they usually pause and pee outside before they go in. So I guess they
are toilet trained - it's just where
they want to go!
