I am constantly worried about my four female ferals (3 7month old kittens and mother) It is freezing outside and they go under my deck instead of the nice cozy heated house I bought them...a big tom cat went in the house and I guess that was enough for them to keep them away from it....I took everything out and washed it but still they stay under my deck where it is cold...I tried my best to make it warm under there, a heated pad, and heat light bulb but it's still cold -- they are very fearful and stressed out over this tom cat...anyone have any suggestions...how I can keep them warm and safe. I tried to let them in but I have other animals and they know it...I even tried putting my animals away and they come in for a minute and run out...I feel so bad....HELP....
