all these ideas were great and I definitely will try at least a couple of them out! I did just try the paper cracker one with Hamburglar, and he absolutely loved it - immediately scampered out to chew on it, even at 4pm! however I would like to let people know that it should be given to their hams under supervision; Hamburglar only chewed a hole big enough to stuff his head in, but once he'd pouched even a little bit of the treats, he couldn't get back out! I had to unfurl one of the ends of the cracker so he could escape. other than being a little ruffled, he was fine. here are some pics I took before he tried to back out and got distressed at not being able to:
I mean, it was adorable and certainly made me laugh but he did need help getting back out, so you may just want to keep an eye on them when they play with the cracker.
