Thank you! I looked through your link and you gave me inspiration! I had a couple of old egg cartons that Hubs suggested we use to make foraging toys. I had no clue how to go about doing it but then this morning after looking through, I figured it out. I cut the carton (a dozen carton) in half, and then in each of the 6 divots I placed either a nutriberry or some cheerios. I then placed balled up newspaper over each so that the closed half carton was stuffed. I kept it closed and hung them with some bird-safe yarn and some D rings I had. Loki seems to be interested so far, they've only been there since this morning. Fingers crossed!!
Thanks again!! I can't wait to try some of the other toys you showed in there!
