The bedroom is very warm in summer. The kittens and the mother cat were overheated in the bedroom. Installed the Vivo cooler with no problems. Used the ice pack from the lunch box while the two ice packs that came with the cooler were frozen. I cycled the fan, raised the blinds, and set it to cool. I had to turn it off after an hour because my husband had a cold. Now I set a timer for an hour every night and we sleep peacefully. Mother and kitten are doing well.
