Home Repair: How to fix this?

[Aqualoon]

I'm a first time cat owner, have had dogs my entire life and currently have a chocolate lab. Figure moving into a new house and I have always liked cats that my aunts or cousins had so figured why not, lets get a cat! Lets just say that I'm much more a dog person and my dog agrees that heat would be awesome - was 50F in the house last night.
