my friend has two cats and has unfortunately moved to an area with a lot of cat poisoning goes on (it was an emergency move she had no choice over the area) so she has decided to keep her cats as indoor cats they are more than happy with this (the one refused to go out anyway) anyway the recent hot weather has caused a problem she can't open the windows for fear the younger one will go out its absolutely sweltering in the house we tried to shut them in the one room today while we worked upstairs with the windows open however her autistic daughter accidentally opened the door and caused a mad panic when we couldn't find where the younger cat was does anyone have any bright ideas what we can use so we can have open windows and safe cats as we will soon be decorating the house and i don't think i will end well unless we can sort something!
