Experienced litter trainers needed

I've taken advice from others as well as do what I did with our bunnies and rats. The rats were by far the easiest to train. My bunnies were already trained, but I did take the advice I got about putting the hay bin over/next to the litter box. They like to do two things at once.

The piggies seem a lot like the bunnies, in that they go and eat at the same time. Our two hay bins are right next to the litter boxes. My girls are about 80% trained. I do notice that one will still go on occasion, in her nest box. But for the most part, they are great. I do still pick up the stray poos and toss them in their litter box too.

We started off with fleece on the bottom of their living area, and wood pellets in their box. It really worked for our other animals. If you have a cage lined with litter, it's important not to use the same litter in the boxes.

You can't really litter train pigs, they will either use a litter box/pan or they won't. The best you can do is provide them with one and hope for the best. They will never completely poo in one place so please don't expect them to exclusively use a pan for all their bathroom needs.
