I use megazorb horse bedding and hay on top and put them in the corners of the cages.
I go through a lot of bowls a day for their food and ready grass.
There are a few tunnels for enrichment in their cages.
I make sure the pigs have ample amounts of bottles between them.
ready grass is not cheap but really good for the pigs teeth..
I use this to absorb the wee and that the hay sits on.
The piggies get monthly nail trims
I brush the pigs with a soft bristle brush.
I weigh the pigs monthly to check their weights. I also make a spreadsheet of the information for my records.
