Joy Ice Cream Cups Grocery Store RattyRat's Review: This is a really fun treat to introduce to a group of rats and watch the game unfold, "who can keep the cone the longest". And it's hilarious to watch a rat carry this big cone around with their head up high looking all proud. Make sure you get the cake cones not the sugar cones. Using the cake cones it is a no fat, low sugar treat that your rats will love!
