What treats DON'T yours like, that you thought they would??? Ours so far: Kix cereal (even crumbled up), strawberry cream cheese, dry catfood. Catfood's not good for them anyway, maybe they already know.
I haven't found any treats that they like yet...tried yogurt, spinach, blueberries and strawberries. They kind of picked up the berries for a second and ran, but then forgot about them a second later! I'll keep trying new things to see what works.
