If your cat is panting excessively on the bed, the first step is to determine if the temperature of the bed or pad is too hot. If it is not, consider adding a cooling mat to the bed. If the temperature of the bed or pad is too hot, you may need to cool down the bed by placing a fan on it or blowing air onto it. Try spraying a cold mist spray bottle full of water onto the mattress and/or sheets.
