This is a common problem that cat owners face. A draught-excluder can help reduce the amount of cold air that is able to enter the house.

You can also purchase draft excluders that fit around the frame of the flap and help reduce drafts. Be aware that they will not stop cold air from entering your home, if you're trying to open the door for your cat.
