For a dig box, would "fuzzy balls" or sponge balls be okay to use? The come in a variety of sizes as well. So I could get ones that wouldn't be swallowed.
I know a lot of people use fleece strips, but I want other options as well. Dirt/sand would be fun, but it can get stuck in a boys, boy parts, so I won't use that.
