People are doin it wrong
Size: 1 Pack, Style: Cone
Cheap and durable and huge. The bad reviews are from people who aren’t using it right. Step 1) plug hole with a smear of peanut butter. 2) put a low calorie but appetizing mix of whatever you want: yogurt, pate, pumpkin puree, blended with frozen veggies on the walls 3) freeze cone for 30 mins. Hole will be sufficiently plugged to add liquid. 4) fill the rest with water or bone broth and freeze overnight to make it a changing ice block.

Quality issues
The first one the squeaker did not work, the second one the seam on the wing had a fault so it didn’t not last more than an hour or two before it was taken away.
