Mine got all kind of toys,
plastic squeeky hot dogs through their teething stage only
big furry animals with long arms and legs so they could play tug with each other or I could hold it and let them tug, (do not tug back just let them pull, they will not pull hard enough to hurt them and not everyday)
all kinds and sizes of furry toys with squeakers
small hard pressed raw hides (through teething stage only, they can get stuck in an adult RR's intestines)
Here's a pic with Rocket and his hoard of toys.

Hope this helps
