Perhaps Indy is feeling maternal. Animals do crazy things sometimes, when they feel the need to be parents. We had a dachsund/chihuahua who once adopted a plum. Kept it by her side for two weeks, exactly where a nursing pup would be. Growled if anyone tried to remove it. Finally, after so much wear (and tooth marks), she sorrowfully gave it up by putting it in a corner and abandoning it. Maybe Indy is chewing things out of an instinct to create nesting material.
