Soft toys

To my knowledge, there's no 100% safe soft toy. Stuffed animals have stuffing, eyes, etc. that can be dangerous for piggies. The only thing I can think of is if they must have soft toys, make them out of fleece, but the piggies could still chew them, I guess...just make them out of solid fleece (like use fleece for the stuffing) and don't put eyes or thing on them. If you have stuffed animals in their cage, check them regularly to make sure the stuffing isn't coming out and they're still safe.

I hope some other people have advice for you on what soft toys they use for their piggies!
