COOL....

A very hot day today and tomorrow's forecast says it will be even warmer tomorrow.

We heard about special cool collars for pet's so we decided to try it out.
Carst is wearing one and it seems to work.
Some kind of crystals in the collar are soaking the water and when the water evaporates slowly it's obvious the temparure of the surroundings of the collar drops.

It has to be soaked in water and works for some hours.

Here's more info. (in Dutch)
