I got these for my parakeets who loved them from day one. They love tossing the popcorn around and then attacking it and shredding it to pieces after eating all the seeds off of it. My rats love eating them and they are great for training treats. My dwarf hamster also like them and will break up the popcorn piece and hide it around his cage. This is a great product but it is quite expensive so I can only buy a bag every couple months or so.
