I recently brought home two Himilayan yr old cats from the local animal shelter. They spent two nights locked in our living room. We opened the doors and the next night they ventured (ran) up into our attic! It is very hot up there and I am worried about their safety. I keep bringing fresh water up and they have food and litter, but will they come out to drink even if they are scared? (Very scared) What should we do? My other three cats spend alot of time up there even when it is very hot, but they are not afraid to come out. Thanks for your opinion.
