What you need
- 1 paper cup or an empty, clean margarine tub
- Pieces of dry pet food, shredded cheese, or any kind of special treats you are allowed to feed to your pet
- Food coloring (optional)
- A freezer
Put some pieces of dry pet food into the bottom of the cup or margarine tub. Add just enough water so that the food is covered. You can make your pet treat more colorful by adding food coloring to the water before you pour it into the container. If you use food coloring do not let your pet take the treat onto any carpeted areas in your home. Put the container in your freezer.
Check the container after about one hour. If the water has not frozen yet, put it back in the freezer and check again in another hour.
After the first layer is frozen, take the container out of the freezer and add something else (we used shredded cheese).
Add a little more water, again so that the food is just covered by liquid. Put the container back into the freezer.
When the last layer has frozen solid, remove the treat from the container. If you used a paper cup, you will probably be able to simply tear the cup away from the ice. If you used a margarine tub, you can set the tub in a bowl of warm water for a minute so that the ice begins to thaw, and the treat will slip out of the tub.
Give the treat to your pet and watch what happens: does your pet sniff or lick it first? Does your pet bat it around with a paw? How long does it take your pet to get to the treats inside?
