Just purchased a gel pad on-line (@$14); it does not require anything except pressure to cool. The inside is water, glycerol, and polyacrylamide--and the outside is terylene and cotton. It's rather soft and not at all 'crinkly' or stiff. I got it for Piper to use in the car when we do short jaunts; lemme tell ya...it works! Since Piper still wanted to rest on my leg, I just laid pad over me and set her on pad and we both enjoyed a cooler, more comfortable ride home. As with other items (chews, etc), the pad is not left out. So far I'm very pleased. |
