Sorry your father does not see things the same way as you do regarding the cat run. Maybe he would feel embarrassed having one because no one else around has one. Are your kittens totally indoor now, or indoor and outdoor? If they are totally indoor, they might not be missing the outdoors as much as you fear. Mine like to sit in windowsills. We also have an enclosed porch - not screened in, but it does have a couple of large windows with deep sills, as well as a door to the outside, so that the cats can look out - and to them, it's like going outside, because it's a different space for them to explore, with different smells and a different temperature from the indoors - and sometimes, when the screens are in, they get the fresh air that way. Again, sorry you are having trouble getting things the way you want them to be. One other thought - just in case it's the money that is stopping your father, is there any way you could earn extra money to put toward the cat run? Or maybe he thinks it will spoil the looks of the property? Good luck in resolving your dilemma.
