What if I never open the windows?

Let’s be clear, we aren’t trying to force our adopters into doing things against their will. The cat’s safety is something we should all be concerned about. When people tell us, “I never open the windows”, we have to ask them: “What about your other family members? Your visitors? Your helper? Workmen who come to fix or clean things?” It is very difficult to guarantee that windows will stay closed, and even a brief mistake is enough to endanger a cat’s safety.
