i made some screens last week............fivers worth of chicken wire, fivers worth of thin wood, some self adhesive velcro, .....that way they can be removed when needed so the windows can be closed. Willows has taken to standing on the coffee table, front paws on the screen so she can watch the world go by and get her fur ruffled by the (slight!) breeze
plenty of water bowls down, ice cubes in to keep cool, changed several times a day
she dosnt worry about the cool lino, seems to prefer hiding under the sofa or coffee table
