so summer has finally hit where I live, and I'm wondering how to keep Isis and saki cool through this heat. neither are overweight, and they have been choosing spots in the shade to rest and such. I have a couple of 14"x14" tiles set on the ground for them to rest upon, should they choose to, since those are generally cooler than the carpet. I used to have marble tiles, but the rabbits thomped one too many times and broke them. we don't have a/c in the main living areas, and locking the cats in the bedrooms doesn't seem fair. I have a few frozen towels that I will be setting out to see if they will like those, and they have multiple watering holes, including a filtered water fountain, but what other ways can I cool them down and encourage them to drink more water?
