I tried these, and my horses played with them, and once they figured out they had to keep chasing it to get a taste, they totally ignored them. I guess they were never bored enough.
I recommend the JOLLY brand if you do buy something like this, though. It's a USA product while the other is imported from Scotland or something. I also used to work for Toklat, Likit's distributer in the western half of the states. Such a rotten company that I don't care to support it, so I also avoid buying anything they sell, which includes Likit... especially after they "let me go." Miserable place to work...sad that the word "Likit" made me think of them again. It's been over a year, but the memory is still too young.
