Hi I was wondering. Should I get my indoor cat gwen up to date on her shots. I would like to try and bring my out door feral in the house. He is so friendly with my dog and me. I dont want him out another year in the cold if i dont have to. I dont know if my feral bell is carrying any thing. It took two years for me to pet him and now he just waits by the door for me. . Also I have a heated Igloo for him out side. But I just saw another cat house that is heated.It is rain poof but was I think that just might blow away. I love my 2 cats. I never thought I could be such a cat lover. I have had dogs all my life.
